Essentially, Saturn restrained Jupiter, preventing it from falling any further towards the sun. Our solar system could have landed up with a 'hot Jupiter'. Many the reason potentially habitable planets are so rare is because Hot Jupiters are so common!
@@rachelar No, it doesn't contradict it. We know that rocky planets had to form close to the Sun, based on their constituents. However, they would not have remained close to the Sun had Saturn not prevented Jupiter heading ever inward towards the Sun. That would have ejected the inner, rocky planets from the solar system.
Potentially habitable planets may not be that rare. Currently, our observation techniques are biased towards large mass planets with short orbital periods (ie hot Jupiters). If we set up our current technology near Alpha Centauri and look towards our solar system, we won't detect the Earth, and we will miss Jupiter and Saturn because we will not observe the star long enough to detect them.
Really interesting, thanks. We think life exists here because we have water, the correct chemicals and are in the goldilocks zone. But there are so many more factors that contributed to our existance. Makes you wonder how rare life is in the universe if all these factors need to come together in the correct ways.
Those factors may be needed for life as we know it. However, just consider how many types of life exist just on Earth... We have life dependent on solar energy, life dependent on chemical/geothermal energy, life existing in the whole spectrum of pressures and temperatures possible. Most life in the universe would not be life as we know it, but life as we have never imagined it. There might be high energy dependent life forms even on hot Jupiters.
@@ExperienceEric Nope... it's because those people are morons who need a mental crutch to cope with the wonders of the amazing universe we live in. Have you ever heard of the puddle quote by Douglas Adams?
What are the chances that a mars sized planet swiped by earth at just the right angle to form the moon and the tides it facilitated contributed to life taking hold on earth!!!!
This episode touches on one of the most interesting of astronomical theories, that of the Earth as a privileged planet, uniquely positioned to be friendly to life. Saturn not only moves Earth into that ideal zone, Jupiter and Saturn stand guard, their sheer size keeping us from being regularly being battered by large asteroids.
Late reply, but check this Wikipedia link (en.wikipedia.org/wiki/Laser_Interferometer_Space_Antenna) "Unlike terrestrial gravitational wave observatories, LISA cannot keep its arms "locked" in position at a fixed length. Instead, the distances between satellites varies significantly over each year's orbit, and the detector must keep track of the constantly changing distance, counting the millions of wavelengths by which the distance changes each second. Then, the signals are separated in the frequency domain: changes with periods of less than a day are signals of interest, while changes with periods of a month or more are irrelevant."
How about this one, Michael: our moon. It could not have formed WITH earth (this includes a Theia collision, since, necessarily that would involve another forming of the earth) because it does not orbit in earth's equatorial plane, and it could not have been captured because its orbit is far too circular to be a captured object. What, therefore, is left? How did it get there?
@@kelly8431 Actually, Michael makes a good point. Don't dismiss it. It's important. In fact, you might want to give the book (written by an older generation), "The Privileged Planet" a read.
@@williammaddock9179 actually, the Theia collision was modeled and found to be a glancing collision, with ejecta orbiting to become the moon, so only one forming and one just recooling enough to form a solid surface that water could accumulate on. Wildly elliptical orbits wouldn't remain stable as the moon formed, they'd either be ejected or strike either the moon or earth.
@@FVLMEN right on. it’s almost indisputable considering all converging lines of evidence coming from myths and an understanding of the electric nature of the cosmos
It includes my favorite Moon Enceladus. Actually my favorite "body" as it were. Also explains the resonance of Moon systems around planets. You could even think of Saturn being its own System.
Without a doubt your channel is one of the best on TH-cam. I even like the way you presented the ad. No disruption of content, no attempt to trick us it was part of the story you were telling and were honest about it. I appreciate it.
Saturn is my favorite too. My dad worked on the Hubble before it was launched, and received copies of the first negatives and prints. The photo of Saturn was stunning. 💛
Glad I found this. The Correlation between Music and the "Resonance" of planets was especially enlightening. The" Music of the Spheres" so to speak. Thank you.
Earth exists because of Saturn since we once were a satellite of him (tidally locked), same as Mars, Neptune and likely Venus. That's why we all share the same spin axis tilt!!!!
I've long held a grudge against Saturn...cuz I had to make a model of the solar system once...it was kinda hard to make Saturn's ring...this video helped me make peace with Saturn. Thanks Dr Becky..;-j
You always learn something when you watch the Dr. Becky channel!! Thank you Dr. Becky for making these concepts accessible and entertaining. Your channel is awesome!! My favorite planet (besides the Earth) is Saturn.
Jupiter's orbital period is 12 years - how many Exo planets with 12 year or longer periods have we detected? Barely a handful. We've hardly been searching for Exo Planets long enough to detect planets with the periods we see in our own solar system. I'm convinced that the "abundance" of hot jupiters is a MASSIVE sampling error - these are by far the easiest planets to find by our current detection methods. I have a feeling that as we search more and we begin detecting more small planets with longer periods, we'll end up majorly revising our models of planetary formation again.
Sauron: "One Ring to rule them all, One Ring to find them. One Ring to bring them all and - " Saturn: "Yo, I'm happy for you, and I'll let you finish, but check _these_ out."
I have to disagree with one point, the bloopers are fun, but my favorite part is the actual videos; complex subjects made understandable for the layman without dumbing it down. And by the way, I love your accent.
I believe static electricity charges are what cause tiny pieces of dust to buildup and combine with other dust particles. A crew member on a space shuttle mission years ago demonstrated this static attraction force with a clear plastic bag of small pieces material that, after shaking it up, the small pieces of material would begin to cling to other small pieces in a matter of seconds. In time gravity will become the major combining force.
Gustav Holst, regarding his composition of The Planets, remarked that Saturn, The Bringer of Old Age, was his favorite movement of the suite. Such a man, weak of nature yet strong of spirit.
I keep falling in love with space more and more as I keep watching and listening to you!! you are amazing and the reason I am able to be sure about me choosing astrophysics in the future..! Thank you
I'm a man of biology and geography, so when I say I've started really getting into astrophysics because of your awesome videos... That's huge 😁 Keep going, loving every bit of it!
I'm fond of Saturn, too: O jeweled giant, so sublime! A spectacle to astound to! The angels blessed you with this sign; They parked their halos around you. But it's not my favorite: O lovely orb of brown and green and blue and white; a shining pearl; at last I’ve seen where I have been; my home, my love, my life, my world.
This video just popped up in my feed. She explained it so well. Obviously knows her subject but explained it so enthusiastically and clearly. I am impressed. Wish my school teachers had been so good 🤩.
the chances of intelligent life on Earth forming on Earth is mind blowing enough. However adding onto that everything that had to happen for Earth, it really is something there is no word for.
. I love how she explains things! I like learning from all sorts of discipline, but most of the time, the presentation always PUTS ME OFF Either too condescending or too vague! . I like how she still talks in a technical manner but offer bits of explanation in the video inserts, to target both more knowledgeable audience, and the tyros in us. She certainly makes a GREAT teacher!
As our sun ages and expands, there will come a time when someone in another star system, looking at our sun, will wonder why we have a hot Jupiter. So my question is, what type are stars are all these hot Jupiters orbiting. Also given the limitations of our current technology to see exoplanets, it follows that a majority of those we find in the early years, will be large planets, close to their star where they have the greatest gravitational effect (to induce a wobble in the star that we can detect) or have the greatest dimming effect as it passes between us and its star.
These observational biases always need to be considered when interpreting results. The populations we find are seriously skewed towards what the methods easily find.
There's a part in Arthur C. Clarke's novel 2001: A Space Odyssey where the Discovery uses Jupiter for a slingshot effect to gain velocity to get to Saturn (I'm not confusing this with the 2010 movie, Hyams took the sequence from the first novel). Clarke notes that the law of conservation of energy is maintained, and Jupiter lost all of the velocity that the Discovery gained. I always though it would be funny to write a story where the accumulation of all the slingshots space ships did using Jupiter to get into the outer solar system would lead to Jupiter slowing down and falling sunward, eventually threatening the Earth. I'm sure you'd need like trillions of slingshots for that to happen, though.
I remember that section. Man, yer talking quintillion territory. I loved the suggestion that the rings of Saturn were created by destroying a moon for the energy needed to get the monolith to our solar system. 🤘
Sorry, but no. When you get a slingshot from a planet, you are stealing its angular momentum, not its orbital velocity. Your story idea doesn't make sense even if your idea was correct. The kinetic orbital energy of Jupiter moving at almost half a kilometre per second is far beyond the energy slingshots could ever steal from it before the sun expands and vaporises Earth.
The most amazing thing about Saturn is that it shares the same axial tilt as Earth and Mars which does not match the Suns axial tilt, which suggests that Saturn, Earth and Mars are not native to this solar system and possibly have been captured as a mini solar system if Saturn was once a brown dwarf star. Doesn't it seem strange that as each one of those planets sit in a closer orbit to our sun that the axial tilt of each planet will be one degree closer to matching the Suns axial tilt meaning Earth 23 deg, Mars 25 deg, Saturn 26 deg. It's as if the Sun's electromagnetic influence is affecting their axial tilt by distance and time which makes me think the capture was recent by geological times.
@@ianw5439 how do you explain that it shares the same axial tilt .. coincidence ? You seriously believe all stars are ongoing nuclear explosions all 300 trillion of them ? The current solar model is like the dumbest thing man has ever dreamed up (next to black holes) and you believe it is factual as if God himself said so, Lol.
Johannes Kepler discovered "music of the spheres", orbital distance and velocity, law of planetary motion, etc. etc. in his 1619 publication "Harmonices Mundi".
'Discovered' seems like to big a word. The Ancients had been talking about that for centuries, if no millenia. Much of what Astronomers did back then was actually 'rediscovering'.
"Music of the Spheres" is also a great episode from the 90s Outer Limits series reboot. Very interesting if you're into space and the way frequencies can affect your body.

Its a pity, I kick myself, only now I am finding this channel. This channel needs more love. The concepts and theories are wonderfully explained Dr. Becky. Me and my kids loved the video.
As I recall it from my days in the field, planetary migration was suggested very soon after the discovery of 51 Peg b - like 1996 or so. We certainly had it as a topic at the NATO ASI at Cargese, Corsica in 1998. Tidal planet/disk interactions was a thing in the theoretical community of the day ;)
Paisley They are keenly interested in detector tech, image processing and data analysis, not to mention the PR aspect of engaging positively with the civilian world.
I've heard that Mercury is the dead core to a former planet so what's to say that it wasn't itself our very own Hot Jupiter that orbited too close to our Sun and either the Sun burnt off all of the gasses or the planet just got too hot for gasses to condense in or around it thereby losing its thick atmosphere?
Thank you Dr. Smethurst, excellent presentation once again. I just finished "Space at the Speed of Light", wonderful book. I am not sure if you gave me any information that I didn't already know but you organized and explained things in a way I previously hadn't seen but I got many new perspectives. When is the next book coming out? I am ready! You don't need a life, write, write, write.
You're right; "life", when used in that sense, is a bit overstated, come to think ... socially waste your time, is what "having a life" often advocates ...
Dr Becky has to be the prettiest big brain smart person on TH-cam. All that brain power and being equally beautiful combined with successful, she's setting the bar awful high for everyone else and not even really trying too!
I remember that Brian Cox's BBC series on the planets mentioned the 'migrating Jupiter' theory, but he didn't explain how it could first move inwards and then out again, which puzzled me. You did better in a fraction of the time! Incidentally, if you watch that series I think you will shriek in horror and disbelief at a howler in Cox's script, accompanied by a distant humming sound from Kepler spinning in his grave.
@Brian Coley As far as I recall, he *described* it but didn't *explain* it. Your own description doesn't explain it either. You say that the formation of Saturn 'arrested' the inward migration of Jupiter, but what needs to be explained is the fact (if the theory is correct) that Jupiter moved *back* from the orbit of Mars to its present position. If he explained this, perhaps you could add his explanation to your synopsis.
@Brian Coley that's partly true that jupiters are the most common because current technology can more readily pick out large planets and current technology can readily pickup wobbles from small star red dwarfs it's much more difficult with large K type stars and up G,F A. But to say they are the most common is not true. Just wait till the technology improves and the detection around K & G Type stars with Earth like planets will be off the charts. And F8 and F9 stars have potential in wide orbits.
Question : is it true that even though we know gravity causes attraction between dust and particles but we do not quite understand what trigger a collapse where planets starts to form?
General consensus is that the dust became charged via friction and ionising radiation from the sun which caused static attractionlike a balloon on your hair and when these bits got big enough gravity took over proper.
@@theemissary1313 Thanks for the reply. Thats the process most commonly explained. If you know of any research papers done on this subject please do share with me...many thanks.
I noticed Becky excused use of Sa'urn with ACCENT rather than DIALECT. So... she is trying to speak "proper" English but her accent fights back? Also rewinding some video to listen this, I notice she said "pa'at" instead of "part". I think. I'm a Finn so I don't have as good ear as native English speakers to hear the difference for sure. English R has so little trill anyway it often sounds just like a lengthening of the vowel.
@@Aurinkohirvi 'Accent' usually refers to just pronunciation, while 'dialect also includes vocabulary and even grammar. There is nothing at all improper about the northern dialect, or any other regional dialect. Even Scots. I have never heard anyone pronounce 'part' as 'pa'at', with the apostrophe representing a glottal stop. Most varieties of English in England are non-rhotic.
@Brainjock OK BJ, one last try... Mars is much smaller than Saturn or Jupiter. It is smaller because Jupiter sat on (Saturn) it and squashed it. It's just a play on the sound of the names of these planets in the Solar System. Depending where you come from, maybe your natural accent prevents 'Saturn' sounding like 'Sat on'. Maybe it's a UK thing. Say it out loud, although I expect after all you effort to understand it, the joke won't be funny any more... Good luck...
My eldest daughter favorite plant is also Saturn. As a four-year-old she dressed up as Saturn for Halloween. She loved to look at the pictures of Saturn in an old book of mine “Pioneer First to Jupiter, Saturn, and Beyond.”
This is fascinating. And seems to fit with a lot old myths and legends, as well as the Fomenko's Saturnian Cosmology. I am not an astronomer, but found this through my study of banned books as an English teacher. What do you think?
Dr Becky, I just found you and I absolutely love your videos! Great information but have you ever considered that the placement of the planets are more of an electromagnetic placement instead of a gravitational placement? I would love to hear your take on this!
I did the Astrophysics elements of my degree in 2004, at the time, the first exo-planets had been confirmed and Hot Jupiters were a new and interesting phenomenon. At the time, my lecture suggested maybe Jupiter had been like a cosmic corset, holding everything in place. Jupiter held the larger gas giants away from the Sun and stopped the rocky planets from being ejected. I now have an image of Jupiter being the stays in the corset and Saturn the laces, forcing the Solar System into the current shape.
Doesn't all this mean that Earth and our system are particularly rare? How many systems have two large gas giants in resonance, with two other gas giants further out also involved? Are we unusual in having four gas giants in the outer systems, with four inner terrestrial planets? If the above is correct, then our existence on Earth may be even more unusual and rare. That would make the frequency of life-bearing planets like Earth very rare... I find that idea very exciting, not least because it makes life on Earth so precious and needing protection!
Our solar system's configuration is quite rare. It is far more common for a solar system to have two or three so-called 'Hot Jupiters' orbiting very close to their star, with a year sometimes being a matter of a few days.
(in jest) so the bloody Trappist system needs to do its piano lessons, that was appalling. In more serious mood that was what i was trying to find somewhere, VERY long time ago i've heard that Jupiter migrated had no clue why or how. Yes that gravitational pull would help stabilize proto-planets and debris belts in good positions. As for why Jupiter / Saturn stopped maybe it was just sheer speed of their orbit? when you get closer to sun you accelerate on your orbit and if you can not decrease the speed you'd catapult out of the orbit (wisdom learned by destroying sol in Universe sandbox squared over many many messy collisions).
@@PaulDormody I like that explanation, thank you Ice and Fire. Yes i can see how it would have been gradually pulled forth by Saturn's proximity, catapulting them both outwards. Maybe both our explanations played some part? but hey mine is just guess work based upon a game so its not even remotely researched.
@@taanbrown4275 i appreciate the thought but i really am not. if you feel you are lacking in smarts just see if you can find some nice documentaries or enthusiasts in field you wish to become more knowledgeable in.

Becky, i dont feel comfortable using someone's first name this casualy) whose video we watched above is very much both actual smart person and enthusiast in space related science (well specific category of it i think - she dose mention it on occasion).
Thank you so much for making such lovely videos. Explaining things so beautifully and making it so easy to understand. Also, Saturn is my favorite planet too now. I used to 1st like it only because of its beautiful ring, now I'd say i know alot more than just that. Love you❤ keep spreading the knowledge.
The joy that astronomy obviously brings you is contagious. I honestly haven't been this excited about astronomy since listening to Carl Sagan as a teenager. That's right, I just compared you favorably to Carl Sagan. You're welcome.
if recent research on how the universe may be a form of learning quantum machine consciousness is onto something, is it possible that planets themselves or the solar system as a whole possess some sort of consciousness? could they, on some level, know what they're doing?
Love the video - well done with the explanations! I've always been interested in planetary migration, since I was a teenager and the idea was first being bandied about in 1980! I have followed the idea, in all its permutations, as best I can through the years, and you did very well explaining the newer ideas, as well as how it all goes together with our ideas of how our solar system got where it is now, and what that might mean for other solar systems out there. Ah yes, the music of the planets, the resonance they have, is one of the things I sometimes play to relax, meditate to calm my nerves, take a short nap, or fall asleep to - it makes for interesting dreams, too, LOL! As an aside, your nail polish is a really cool pearlescent shade that looks much darker from some angles than from straight on, and I really love it! My preference for nail polish has always been dark, midnight blue, and that's why I noticed yours first, because at one angle, it really looks like my fave, instead, LOL!

I once built a Dobsonian reflector scope that was pretty bad and probably D-worthy in school, but it was good enough to see the rings of Saturn and the Galilean moons of Jupiter. The experience helped reinforce my belief in popular astronomy, not that there was ever any doubt.

Sa'ern or Sa'urn? This is one Finn who isn't. The Latin name is Sāturnus, and we Finns borrowed it as Saturnus, the English as Saturn. Similarly, the Latin name Mercurius we Finns borrowed as Merkurius and the English as Mercury. So yeah, we both changed it a little, but so commonly used names we easily recognize when English speakers say Mercury or Saturn. For an English speaker it is harder to figure what Merkurius is though, if a Finn speaking English does not notice to use the English form of the name. And this doesn't apply to Finnish only, Latin (and other) names have plenty of forms in the many languages of Earth, even more in dialects. But sure, listening whole sentence or speech, it becomes apparent, what she is talking about. I did hear her use word "accent" rather than "dialect" to excuse "Sa'urn". Is she trying to speak litteral English or her actual dialect? Speaking or writing your dialect, going with Sa'urn is not an error, of course you can use it. If you intend to speak pure dialect, you should use it. If you have an accent and try to speak litteral language, then I think you should go with Saturn with T. I'm in favor of Saturn with T. Just because I think that's better treatment for names, to not alter it much (any more). And got the idea she thinks so too.
@@Aurinkohirvi There is a difference between a dialect and an accent. She has an accent that drops Ts in certain circumstances or turns them into a glottal stop. Some American accents do the same.
@@Aurinkohirvi She is from Lancashire, but in that region accents are very regional. In the US, Floridians also do the T-dropping thing in certain areas.

Those factors may be needed for life as we know it. However, just consider how many types of life exist just on Earth... We have life dependent on solar energy, life dependent on chemical/geothermal energy, life existing in the whole spectrum of pressures and temperatures possible.

Late reply, but check this Wikipedia link (en.wikipedia.org/wiki/Laser_Interferometer_Space_Antenna)
"Unlike terrestrial gravitational wave observatories, LISA cannot keep its arms "locked" in position at a fixed length. Instead, the distances between satellites varies significantly over each year's orbit, and the detector must keep track of the constantly changing distance, counting the millions of wavelengths by which the distance changes each second. Then, the signals are separated in the frequency domain: changes with periods of less than a day are signals of interest, while changes with periods of a month or more are irrelevant."
How about this one, Michael: our moon. It could not have formed WITH earth (this includes a Theia collision, since, necessarily that would involve another forming of the earth) because it does not orbit in earth's equatorial plane, and it could not have been captured because its orbit is far too circular to be a captured object.

Jupiter's orbital period is 12 years - how many Exo planets with 12 year or longer periods have we detected? Barely a handful. We've hardly been searching for Exo Planets long enough to detect planets with the periods we see in our own solar system. I'm convinced that the "abundance" of hot jupiters is a MASSIVE sampling error - these are by far the easiest planets to find by our current detection methods. I have a feeling that as we search more and we begin detecting more small planets with longer periods, we'll end up majorly revising our models of planetary formation again.

Big up doc, your enthusiasm is always infections..
Love the singing and the bloopers, it makes for good human interface.. keep up the good work 👌
I have to disagree with one point, the bloopers are fun, but my favorite part is the actual videos; complex subjects made understandable for the layman without dumbing it down. And by the way, I love your accent.
I believe static electricity charges are what cause tiny pieces of dust to buildup and combine with other dust particles. A crew member on a space shuttle mission years ago demonstrated this static attraction force with a clear plastic bag of small pieces material that, after shaking it up, the small pieces of material would begin to cling to other small pieces in a matter of seconds. In time gravity will become the major combining force.
Gustav Holst, regarding his composition of The Planets, remarked that Saturn, The Bringer of Old Age, was his favorite movement of the suite. Such a man, weak of nature yet strong of spirit.
I keep falling in love with space more and more as I keep watching and listening to you!! you are amazing and the reason I am able to be sure about me choosing astrophysics in the future..! Thank you

4:40 Wait, wait, wait...polar and equatorial orbits in one system? WHERE!?!?! I want to read more about this!
As our sun ages and expands, there will come a time when someone in another star system, looking at our sun, will wonder why we have a hot Jupiter. So my question is, what type are stars are all these hot Jupiters orbiting. Also given the limitations of our current technology to see exoplanets, it follows that a majority of those we find in the early years, will be large planets, close to their star where they have the greatest gravitational effect (to induce a wobble in the star that we can detect) or have the greatest dimming effect as it passes between us and its star.
These observational biases always need to be considered when interpreting results. The populations we find are seriously skewed towards what the methods easily find.

I love how much joy have speaking about this subject. It's such a treat and the 20 minutes just flies by.
There may be a musical "resonance" between Jupiter and Saturn, but there's no Autotune.
There's a part in Arthur C. Clarke's novel 2001: A Space Odyssey where the Discovery uses Jupiter for a slingshot effect to gain velocity to get to Saturn (I'm not confusing this with the 2010 movie, Hyams took the sequence from the first novel). Clarke notes that the law of conservation of energy is maintained, and Jupiter lost all of the velocity that the Discovery gained. I always though it would be funny to write a story where the accumulation of all the slingshots space ships did using Jupiter to get into the outer solar system would lead to Jupiter slowing down and falling sunward, eventually threatening the Earth. I'm sure you'd need like trillions of slingshots for that to happen, though.
I remember that section. Man, yer talking quintillion territory.
I loved the suggestion that the rings of Saturn were created by destroying a moon for the energy needed to get the monolith to our solar system. 🤘
Sorry, but no. When you get a slingshot from a planet, you are stealing its angular momentum, not its orbital velocity.
Your story idea doesn't make sense even if your idea was correct. The kinetic orbital energy of Jupiter moving at almost half a kilometre per second is far beyond the energy slingshots could ever steal from it before the sun expands and vaporises Earth.
@@Chris.Davies I hedged it with "quintillion" bc I didn't want to explain "duotauvingintillion". 🙂
She is so human in her presentation that we can relate to her smiles and emotions with her.Got to love that.
The most amazing thing about Saturn is that it shares the same axial tilt as Earth and Mars which does not match the Suns axial tilt, which suggests that Saturn, Earth and Mars are not native to this solar system and possibly have been captured as a mini solar system if Saturn was once a brown dwarf star.
Doesn't it seem strange that as each one of those planets sit in a closer orbit to our sun that the axial tilt of each planet will be one degree closer to matching the Suns axial tilt meaning Earth 23 deg, Mars 25 deg, Saturn 26 deg. It's as if the Sun's electromagnetic influence is affecting their axial tilt by distance and time which makes me think the capture was recent by geological times.
This is an interesting theory!
Saturn was never a brown dwarf! Not even close.

You answered a lot of questions I've always wondered about our solar system and other solar systems. Thanks.
As I recall it from my days in the field, planetary migration was suggested very soon after the discovery of 51 Peg b - like 1996 or so.
We certainly had it as a topic at the NATO ASI at Cargese, Corsica in 1998. Tidal planet/disk interactions was a thing in the theoretical community of the day ;)

Video starts at 6:00 - after repeating all the stuff everyone has known for a long time.
I've heard that Mercury is the dead core to a former planet so what's to say that it wasn't itself our very own Hot Jupiter that orbited too close to our Sun and either the Sun burnt off all of the gasses or the planet just got too hot for gasses to condense in or around it thereby losing its thick atmosphere?
2:50 that is an intuitive statement. Try: Lighter elements get pushed out by the solar radiation, leaving the heavier elements.

I remember that Brian Cox's BBC series on the planets mentioned the 'migrating Jupiter' theory, but he didn't explain how it could first move inwards and then out again, which puzzled me. You did better in a fraction of the time! Incidentally, if you watch that series I think you will shriek in horror and disbelief at a howler in Cox's script, accompanied by a distant humming sound from Kepler spinning in his grave.
@Brian Coley Jupiter combined with the sun would have pulled Jupiter deeper in .
@Brian Coley As far as I recall, he *described* it but didn't *explain* it. Your own description doesn't explain it either. You say that the formation of Saturn 'arrested' the inward migration of Jupiter, but what needs to be explained is the fact (if the theory is correct) that Jupiter moved *back* from the orbit of Mars to its present position. If he explained this, perhaps you could add his explanation to your synopsis.
@Brian Coley that's partly true that jupiters are the most common because current technology can more readily pick out large planets and current technology can readily pickup wobbles from small star red dwarfs it's much more difficult with large K type stars and up G,F A. But to say they are the most common is not true. Just wait till the technology improves and the detection around K & G Type stars with Earth like planets will be off the charts. And F8 and F9 stars have potential in wide orbits.
@@osmosisjones4912 read your comment... again
Question : is it true that even though we know gravity causes attraction between dust and particles but we do not quite understand what trigger a collapse where planets starts to form?
General consensus is that the dust became charged via friction and ionising radiation from the sun which caused static attractionlike a balloon on your hair and when these bits got big enough gravity took over proper.

Also rewinding some video to listen this, I notice she said "pa'at" instead of "part". I think. I'm a Finn so I don't have as good ear as native English speakers to hear the difference for sure. English R has so little trill anyway it often sounds just like a lengthening of the vowel.

@Brainjock OK BJ, one last try... Mars is much smaller than Saturn or Jupiter. It is smaller because Jupiter sat on (Saturn) it and squashed it. It's just a play on the sound of the names of these planets in the Solar System. Depending where you come from, maybe your natural accent prevents 'Saturn' sounding like 'Sat on'.

This is fascinating. And seems to fit with a lot old myths and legends, as well as the Fomenko's Saturnian Cosmology. I am not an astronomer, but found this through my study of banned books as an English teacher. What do you think?
Dr Becky, I just found you and I absolutely love your videos! Great information but have you ever considered that the placement of the planets are more of an electromagnetic placement instead of a gravitational placement? I would love to hear your take on this!
I think that both have a role, Gravity makes things move and the electromagnetic field makes them stable and safe.
Planets. like stars, are overall electrically neutral. EM has no effects on their place of formation, nor why they stay there.
I did the Astrophysics elements of my degree in 2004, at the time, the first exo-planets had been confirmed and Hot Jupiters were a new and interesting phenomenon. At the time, my lecture suggested maybe Jupiter had been like a cosmic corset, holding everything in place. Jupiter held the larger gas giants away from the Sun and stopped the rocky planets from being ejected. I now have an image of Jupiter being the stays in the corset and Saturn the laces, forcing the Solar System into the current shape.
Doesn't all this mean that Earth and our system are particularly rare? How many systems have two large gas giants in resonance, with two other gas giants further out also involved? Are we unusual in having four gas giants in the outer systems, with four inner terrestrial planets?
If the above is correct, then our existence on Earth may be even more unusual and rare. That would make the frequency of life-bearing planets like Earth very rare... I find that idea very exciting, not least because it makes life on Earth so precious and needing protection!
Our solar system's configuration is quite rare. It is far more common for a solar system to have two or three so-called 'Hot Jupiters' orbiting very close to their star, with a year sometimes being a matter of a few days.
(in jest)
so the bloody Trappist system needs to do its piano lessons, that was appalling.
In more serious mood that was what i was trying to find somewhere, VERY long time ago i've heard that Jupiter migrated had no clue why or how. Yes that gravitational pull would help stabilize proto-planets and debris belts in good positions.
As for why Jupiter / Saturn stopped maybe it was just sheer speed of their orbit? when you get closer to sun you accelerate on your orbit and if you can not decrease the speed you'd catapult out of the orbit (wisdom learned by destroying sol in Universe sandbox squared over many many messy collisions).
whoa cool
Jupiter would ave accelerated after clearing the dust and debris in its path, that and the pull from Saturn every 2 orbits.
@@PaulDormody
I like that explanation, thank you Ice and Fire.

Just listening to you presenting these complex topics absolutely fascinates me as I often loose track of the subject and just immerse in to the passion with which you talk....
Well, just so you know, this is one Yank who's just fine with your pronunciation of Sa'ern.
Fred
Sa'ern or Sa'urn? This is one Finn who isn't.
The Latin name is Sāturnus, and we Finns borrowed it as Saturnus, the English as Saturn. Similarly, the Latin name Mercurius we Finns borrowed as Merkurius and the English as Mercury. So yeah, we both changed it a little, but so commonly used names we easily recognize when English speakers say Mercury or Saturn. For an English speaker it is harder to figure what Merkurius is though, if a Finn speaking English does not notice to use the English form of the name. And this doesn't apply to Finnish only, Latin (and other) names have plenty of forms in the many languages of Earth, even more in dialects. But sure, listening whole sentence or speech, it becomes apparent, what she is talking about.
I did hear her use word "accent" rather than "dialect" to excuse "Sa'urn". Is she trying to speak litteral English or her actual dialect? Speaking or writing your dialect, going with Sa'urn is not an error, of course you can use it. If you intend to speak pure dialect, you should use it. If you have an accent and try to speak litteral language, then I think you should go with Saturn with T.
I'm in favor of Saturn with T. Just because I think that's better treatment for names, to not alter it much (any more). And got the idea she thinks so too.
@@Aurinkohirvi There is a difference between a dialect and an accent. She has an accent that drops Ts in certain circumstances or turns them into a glottal stop. Some American accents do the same.
Celebrate your roots. Even windbags fully understand you.
@@Markle2k Yeah I know they aren't the same. I'm just not so familiar with English dialects. Can you say what kind of an accent is it?
@@Aurinkohirvi She is from Lancashire, but in that region accents are very regional. In the US, Floridians also do the T-dropping thing in certain areas.

Personally, my favorite planet is the one I can breathe on.
Dr.B is so intelligent and engaging and quite fit as well! Woo!
I'm just half way of the video and already impressed by the explanation of how the solid planets formed closed to the sun. Thanks Dra. BECKY 👏👏
"When you take a ball of pizza dough and you throw it up your head and set it spinning", just like how we all do with our homemade pizza, right? :P
Saturn is your prefer star maybe because you are reptile 🧐
No, Doctor, you're pronouncing the "T" in Saturn just fine. You're dropping the "R". But all Brits do that unless it's at the beginning of the word. Anyway, I think your Northumbrian(?) accent is great. Just be yourself - and keep saying "dust". We've made it into a drinking game here in the States. :) Yay! Doost! ((Falls over drunk.))
She pronounces the "T" the same way that upstate New Yorkers pronounce their Ts, e.g. "kih-en" for "kitten."
I think it's cute.
@@KutWrite Agreed.
I love your videos. So insightful for those of us that don't have time to research this type of material at the depths we would like. Because of this I tend to watch the ads that YT forces, even though this has a paid promotion. I sadly have found myself skipping more and more ads on not just your videos but all YT vids because I refuse to watch a 10+ minute ad, and they hit me with two over 1 hour long ads for this video. What the heck are they thinking forcing ads that long? They are destroying your ability to monetize your content.
I always thought as a kid that this planets are positioned perfectly so earth can create life. They are there for a purpose.
