Over the course of various episodes, Stephen's told Alan: There are only eight planets, Pluto's out; there's no moon, it's really a small planet; and there are two moons. But surely, if one moon is a planet, that makes nine planets, and one moon.
1. Cruithne and its ilk aren't really moons; they're asteroids orbiting the Sun whose orbits are stabilized by Earth's gravity. 2. The current IAU definition of "planet" doesn't require the planet to have evicted every other body in its orbit; it's just that the stuff still stickin around needs to be "controlled" by the planet's gravity, like the Moon or Cruithne.
A reasonable definition of a double planet would be that the common center of mass is outside the more massive planet. Jupiter I believe have that distinction relative to the Sun, and Charon relative to the Pluto. So if Pluto were to be reinstated as a planet, there would be 10 planets, as the Moon-Earth system orbits around a point beneath the surface of the Earth.
@@57thorns but the moon is drifting away from the earth, and the barycentre will thus eventually leave the earth too...what then? Clock's ticking, you've got less than 4 billion years to come up with an answer XD

Sounds like a perfect opportunity to capture one and actually make it a permanent moon/satellite. People obviously need to play more Kerbal Space Program 🚀
The other planet wasn't called earth, so even if you consider them separate still (how?) then there is still only one earth. But both of those planets were made of smaller things, shall we say earth does not exist and that it is in fact just a very tight cluster of asteroids and dust? Of course not, the moon has one earth.
@@eleSDSU Sandi, herself, says the other planet is called Thea. So even if they were still apart, the Moon would have one Earth and one Thea. But since they ARE supposedly combined, and that combination is called "the Earth," then the Moon has one Earth. And birds are NOT dinosaurs any more than mammals are reptiles. I don't care WHAT "rock-star" paleontologists say to get their papers published and grants approved.
2:40 Alan Davies performs the first recorded live-action performance of Hirohiko Araki's Torture Dance, 15 years before its animation by David Production.
As a semi-trained astronomer, I still maintain that there is one moon. The mini-moons don't really orbit the earth, and the idea that the earth's planetary system means the moon isn't a moon is just silly.
Exactly. It's just semantics. Essentially all they can say is "there's more than one moon if you change the common understanding of the word, rendering it useless, and therefore the statement "there's more than one moon" becomes completely uninteresting"
The Moon only has one Earth. The other planet that merged with Earth had a different name, so it was not Earth. Regardless, the story about Sandy being at Mission Control is CRAZY awesome.
Not sure how your logics work here, but the whole point is that both celestial bodies had (has) parts of both :p So the Moon has some Earth and the Earth has some Moon. Which means The Earth has two The Moons, which are not moons but binary planets.
SebSk The logic is that until the second planet collided with the first, there was no “Earth”. The Earth is a byproduct of the collision. Take salt for example. If you have either sodium, or you have chlorine you don’t have salt. Therefor the moon has one Earth.
Not quite. If the theory about two planet-sized objects colliding 4.5 billion years ago is true, and the Earth is a combination of those two objects, then the Moon still only has one earth because the two objects aren't separate anymore.
What fascinates me is the fact that someone at Nasa at some point in the 80s went "Well, here's some old tapes, I wonder what's on them? Nah, probably nothing important, we can tape over them". I mean, someone decided to tape over what is arguably the single most important piece of film recorded up until that point (possibly still is). you can literally take any other piece of film in the world, and it would be a smaller loss than that. This is probably the instance of the worst possible decision someone could ever make.
Well, not really when you think about it. First of all, those were originals, footage has been copied countless times on better mediums since then. It's like with other historical photos - we don't have negatives being kept, we just copy the pictures over and over again in different mediums. The other thing is, those tapes were the ones in the camera on the moon - things shown on the TV were signals received and were copies themselves. And it is quite possible that in the 80's when the ORIGINAL tapes were overwritten that people had a choice - to commission tapes for specialized cameras used on the moon 20 years ago, or simply rewrite over the existing ones that have no scientific value. There was absolutely no reason to keep the original tapes as the footage was copied on better mediums that allowed us to make the whole thing of much better quality (various filters and montages etc.), it didn't have any scientific value in the first place and finding a tape that would fit a 20 year old specialized camera was simply way too expensive. People who use old style film for ordinary cameras know how expensive it is in the day of modern digital cameras, let alone some very special limiter series tapes that work on a single model of camera.
@@Wustenfuchs109 They weren't copied to better mediums though. The best we have of the whole thing is from the significantly lower-quality conversion to live TV.
It brings me endless joy that in the scientific vernacular, both "Spaghettification" (what is thought to happen to bodies that are ripped apart when crossing the event horizon of a black hole) and "The Big Splat" (the collision that formed todays earth and moon) are part of accepted legitimate scientific nomenclature.
QI: Question with obvious answer. Alan: Obvious answer QI: *SIREN* YOU FOOL Alan: But it's obvious QI: No, it depends on what theory or definition you subscribe to Me at home: So Alan was technically correct then by a certain theory or definition?
Cruithne isn't a moon. It's an asteroid that just has a co-orbital config with Earth. It doesn't orbit the Earth. In something like 5000 years it might start orbiting the Earth but for now it's not a moon. We do get mini moons from time to time that spin off us after some time though.
Cruithne is an asteroid that is "co-orbital" with the Earth relative to the Sun but is not actually IN the Earth's orbit, making Alan absolutely correct.
Fascinating story from Sandi at the end there, being present at such a momentous event would be spectacular. My dad remembers in great detail where he was when JFK was shot, and when Armstrong set foot on the moon, but the stories aren't quite that cool. Also, side note, Cariad's hairstyle in that last clip looks like Princess Leia's in The Empire Strikes Back and she is even more gorgeous with it.
I know people question Sandi taking over for Stephen but then you learn that she has just as many crazy stories and anecdotes as Stephen did and honestly I don't think you need to worry
Regarding the "no moon, it's actually a planet" and "the earth orbits the moon too", the center of mass that they both orbit is below the surface of the earth always, so no, it's definitely the moon orbiting the earth and not the other way around.
Well, technically speaking, isn't saying one body orbits another a simplification? In the end they are both always inside each other's gravitational spheres, moving arround the mutual center of their mass, so what if it happens to be inside one of them?
Everything orbits everything else. It's just simpler to say the earth orbits the sun, and the moon orbits the earth, than saying anything else. The sun does, technically, orbit the earth, but the orbital paths of the rest of the solar system are so much harder to conceptualise as orbiting earth.
Not really, some don't have moons and other are in such size disparity that they have cleared their path of any object even remotely comparable in size, for example Jupiter or Mercury. Our case is different and more like the Pluto-Charon case than the other planets because our moon is huge for a moon or maybe we (and Venus, Mars, etc.) should be in a different category from Saturn, Jupiter and other giants, after all we [Earth] are as different from an asteroid as they are from us. Planet is not a great word.
@@eleSDSU: Planet is an excellent word. Acting as if applying subcategories to something makes it no longer a part of the broader category as well is the problem (especially when subcategories already exist for the other 8: inner planets & gas giants!). All squares are rectangles; all dwarf planets are planets.
Pretty much all of this is QI bending or misinterpreting the actual definitions (in different ways) to make trick questions. Cruithne does not orbit the Earth. It orbits the Sun but, due to Earth's gravitational influence, it takes roughly the same time as the Earth to do so, which makes it appear to behave as a moon, even though it isn't. At any one time there may be thousands of small rocks in orbit around Earth. Those could be classed as moons as there is no formal limit for the minimum size of a moon. In practise only objects of at least ~1km diameter seem to be counted, which means the Earth only has one moon. There definitely seems to be a misunderstanding of the "cleared its neighbourhood of smaller objects" criterion. It's about which object is gravitationally dominant. As to whether Earth qualifies, the Moon is held in orbit, objects such as Cruithne are held in resonant orbits (i.e. they orbit the Sun in the same time as Earth, or ratio thereof) due to Earth's influence, and any other nearby objects would either be quickly thrown away, collide with Earth, or be captured into an orbit or resonance, so Earth counts as a planet. It so dominates the Moon's gravity that to consider them binary planets (as argued here) is almost nonsensical. For systems such as Pluto/Charon, they are much closer in mass, so calling them a binary would make more sense. However they don't satisfy said criterion, so at best they would be binary dwarf planets. There's no formal limit on where a system with two objects of similar mass are similar enough to be called a binary. One proposed idea is to look at whether the barycentre (centre of their orbits around each other) is inside the larger object or not, however that has problems as the distance between objects also affects that. Under that definition, Pluto and Charon would be a binary dwarf planet, Earth and Moon would be planet and moon, but the Sun and Jupiter would be a binary.
There was one episode where Rich Hall re-appeared and had points deducted from an answer he gave in a previous appearance which was subsequently proven to be incorrect due to new evidence. I think it had something to do with either the moon or moons of one of the other planets.
There is no TH sound in Irish. When you see a H, it means that the letter in front of it is silent. In fact, there used to be no Hs in Irish, right up to the invention of the typewriter. I silent letter used to be indicated by a dot above it but typewriters couldn't print the dot. So, they started indicating a silent letter by putting a H after it.
I will never tire of Stephen's laboured, adamant delivery of 'Because it was discovered in 199-****ing-4!'
It was actually discovered in 1986. What they discovered in 1997 was its orbit: and what the QI researchers misunderstood is that it orbits the Sun, not the Earth, so it's not a moon.

1. Cruithne and its ilk aren't really moons; they're asteroids orbiting the Sun whose orbits are stabilized by Earth's gravity.
2. The current IAU definition of "planet" doesn't require the planet to have evicted every other body in its orbit; it's just that the stuff still stickin around needs to be "controlled" by the planet's gravity, like the Moon or Cruithne.
BINGO!!!
A reasonable definition of a double planet would be that the common center of mass is outside the more massive planet. Jupiter I believe have that distinction relative to the Sun, and Charon relative to the Pluto. So if Pluto were to be reinstated as a planet, there would be 10 planets, as the Moon-Earth system orbits around a point beneath the surface of the Earth.
@@57thorns but the moon is drifting away from the earth, and the barycentre will thus eventually leave the earth too...what then?
Clock's ticking, you've got less than 4 billion years to come up with an answer XD
Alright calm down, Moon Nerd
bear in mind this made in 2005, in the mid to late 2000s scientists didn't have as much information and much like with planets were saying things were moons that weren't really.
Sandi at the end: "Well please, come on. Pick something". Making the uninteresting part interesting. Well done, Sandi and QI!
I like the production value of what could have been a really quick edit of clips! Much more than expected!
I love you QI TH-cam person
love you right back💟😊
Is it you Jane ? ❤️
100% I agreement with Tom Sad Hedge.
There are none. The moon isn't a moon.
Jimmy: "We need to tell people!"
I love this. The answer keeps changing because they discover new info because that's how science works.
I love Sandy's casual humility.
Yes she is a great improvement on SF who always seemed as though HE knew what he was reading (which was not always correct in any case!)
Everyone: Nobody can replace Stephen on Qi!
Sandi: Hold my Carlsberg.
Is Carlsberg still probably the best lager in the world if it’s on the Moon? 🤔🤔🤔
She is how I was introduced to the show. It's like saying Eccleston being my first Doctor.
@@kisbie best lager in the solar system
@@kalakritistudios I will seriously show my age by saying the delightfully batty Tom Baker was my first Doctor. But then I don't really count any of the others except David Tennant anyway ...
@@lilymarinovic1644 Well, ma'am, you're a veteran Whovian. My Greetings!💖
Love Sandy's story at the end. XXX
I love these compilations.
It really should've been Rich vs. the moon because he was much more upset with it over the years.
That is the coolest and cutest Moon Landing story that I have ever heard.
Sounds like a perfect opportunity to capture one and actually make it a permanent moon/satellite. People obviously need to play more Kerbal Space Program 🚀
The moon still has one earth, even if the collision resulted in a fusion and we originally were 2 planets how we are 1, that is what fusion means
The other planet wasn't called earth, so even if you consider them separate still (how?) then there is still only one earth.
But both of those planets were made of smaller things, shall we say earth does not exist and that it is in fact just a very tight cluster of asteroids and dust? Of course not, the moon has one earth.
I'm pretty sure it was a joke
@@BruceNJeffAreMyFlies you are as thick as syrup. The Moon has 2 Earths the same way birds are dinosaurs.
@@eleSDSU Sandi, herself, says the other planet is called Thea. So even if they were still apart, the Moon would have one Earth and one Thea. But since they ARE supposedly combined, and that combination is called "the Earth," then the Moon has one Earth.
And birds are NOT dinosaurs any more than mammals are reptiles. I don't care WHAT "rock-star" paleontologists say to get their papers published and grants approved.

You should add captions to indicate the series/year.
As a semi-trained astronomer, I still maintain that there is one moon. The mini-moons don't really orbit the earth, and the idea that the earth's planetary system means the moon isn't a moon is just silly.
Exactly. It's just semantics. Essentially all they can say is "there's more than one moon if you change the common understanding of the word, rendering it useless, and therefore the statement "there's more than one moon" becomes completely uninteresting"
Another fantastic compilation, thank you. Sorry Sandi, I'll pick something now, I just wanted to wait to find out what you had to say :-)
The Sandy bit at the end: BLOODY BRILLIANT!! XD XD XD
"It's called THE MOON." Love this line...
The Moon only has one Earth. The other planet that merged with Earth had a different name, so it was not Earth.
Regardless, the story about Sandy being at Mission Control is CRAZY awesome.
Not sure how your logics work here, but the whole point is that both celestial bodies had (has) parts of both :p
So the Moon has some Earth and the Earth has some Moon.
Which means The Earth has two The Moons, which are not moons but binary planets.
SebSk
The logic is that until the second planet collided with the first, there was no “Earth”. The Earth is a byproduct of the collision.
Take salt for example. If you have either sodium, or you have chlorine you don’t have salt. Therefor the moon has one Earth.
but why do we call natural satellites moons then, if titan is a moon of saturn then saturn is the ”earth” of titan
Not quite. If the theory about two planet-sized objects colliding 4.5 billion years ago is true, and the Earth is a combination of those two objects, then the Moon still only has one earth because the two objects aren't separate anymore.
The idea of Earth and Thea being merged together is indeed Quite Interesting. Brings in questions of which life coming from which one.
poor Alan, just cant catch a break.. lmao
The Blue Whale and The Moon are such stumbling blocks for Alan
"It's called THE moon."
What fascinates me is the fact that someone at Nasa at some point in the 80s went "Well, here's some old tapes, I wonder what's on them? Nah, probably nothing important, we can tape over them". I mean, someone decided to tape over what is arguably the single most important piece of film recorded up until that point (possibly still is). you can literally take any other piece of film in the world, and it would be a smaller loss than that. This is probably the instance of the worst possible decision someone could ever make.
Well, not really when you think about it. First of all, those were originals, footage has been copied countless times on better mediums since then. It's like with other historical photos - we don't have negatives being kept, we just copy the pictures over and over again in different mediums. The other thing is, those tapes were the ones in the camera on the moon - things shown on the TV were signals received and were copies themselves. And it is quite possible that in the 80's when the ORIGINAL tapes were overwritten that people had a choice - to commission tapes for specialized cameras used on the moon 20 years ago, or simply rewrite over the existing ones that have no scientific value.
There was absolutely no reason to keep the original tapes as the footage was copied on better mediums that allowed us to make the whole thing of much better quality (various filters and montages etc.), it didn't have any scientific value in the first place and finding a tape that would fit a 20 year old specialized camera was simply way too expensive. People who use old style film for ordinary cameras know how expensive it is in the day of modern digital cameras, let alone some very special limiter series tapes that work on a single model of camera.
@@Wustenfuchs109 They weren't copied to better mediums though. The best we have of the whole thing is from the significantly lower-quality conversion to live TV.
It brings me endless joy that in the scientific vernacular, both "Spaghettification" (what is thought to happen to bodies that are ripped apart when crossing the event horizon of a black hole) and "The Big Splat" (the collision that formed todays earth and moon) are part of accepted legitimate scientific nomenclature.
QI: Question with obvious answer.
Alan: Obvious answer
QI: *SIREN* YOU FOOL
Alan: But it's obvious
QI: No, it depends on what theory or definition you subscribe to
Me at home: So Alan was technically correct then by a certain theory or definition?
Not correct enough hehe
“How many Earths does the moon have?”
Alan: no you’re just screwing with me
Because it was discovered in 19 ninety f###### 4! You have to love it when Stephen cracks
WOW. Holding the hand of Armstrong's sect on THE day. WOW. Just WOW
Whoever makes these intros
I love how Carr looks genuinely disgusted when being told the Earth doesn’t have just one moon.
Cruithne isn't a moon. It's an asteroid that just has a co-orbital config with Earth. It doesn't orbit the Earth. In something like 5000 years it might start orbiting the Earth but for now it's not a moon. We do get mini moons from time to time that spin off us after some time though.
Good info, thanks😊👍
a quasi-satellite :)
Forgot how much I appreciated Jeremy Hardy.
Oh god this series of questions haunted me for years.
Cruithne is an asteroid that is "co-orbital" with the Earth relative to the Sun but is not actually IN the Earth's orbit, making Alan absolutely correct.
Perhaps that wasn't really discovered until sometime after this show aired
@@yellowbelly7863 Its orbit was determined in 1997. It is classed as an Aten asteroid which is, by this definition, Earth orbit crossing.
As discovered in 2014. Takes a long time to determine things sometimes.
Aww young Alan Davis was so adorable
Fascinating story from Sandi at the end there, being present at such a momentous event would be spectacular. My dad remembers in great detail where he was when JFK was shot, and when Armstrong set foot on the moon, but the stories aren't quite that cool.
Also, side note, Cariad's hairstyle in that last clip looks like Princess Leia's in The Empire Strikes Back and she is even more gorgeous with it.
“Yes but Alan that was last year. There have been 3 more discovered!” 🤣🤣🤣🤣🤣
Today I learned:
1. NASA used to be concerned with saving money
2. Neil Armstrong had a secretary.
Sandi boasting about her charmed life❤❤❤
Alan has a dispute with The Moon(s), Rich has a war with it.
I'm convinced you could put Alan's face on any picture and it somehow works...
That's such a lovely story!
Alan is adorbs 🥰
🤣 Sandi at the end 🤣 I think if the question ever comes up again then answer needs to be "We have no bloody idea!"
best show ever .
How many points has Alan lost to the question "How many moons does the Earth have?" over the years?
That is so cool to find out where Sandi was during the first moon landing🌛💛
I love Alan's face "I'm going to die"!!!
Sandi's story about the moon landing is priceless.
I know people question Sandi taking over for Stephen but then you learn that she has just as many crazy stories and anecdotes as Stephen did and honestly I don't think you need to worry
Regarding the "no moon, it's actually a planet" and "the earth orbits the moon too", the center of mass that they both orbit is below the surface of the earth always, so no, it's definitely the moon orbiting the earth and not the other way around.
Well, technically speaking, isn't saying one body orbits another a simplification? In the end they are both always inside each other's gravitational spheres, moving arround the mutual center of their mass, so what if it happens to be inside one of them?
Everything orbits everything else. It's just simpler to say the earth orbits the sun, and the moon orbits the earth, than saying anything else. The sun does, technically, orbit the earth, but the orbital paths of the rest of the solar system are so much harder to conceptualise as orbiting earth.
Relativity is not your thing I'll guess.
Best video on here
So can we ask any conspiracy theorists, "OK, which moon didn't we land on?"
8:15 By that standard, none of the planets with moons are planets, because they haven't cleared their orbits of their moons.
Not really, some don't have moons and other are in such size disparity that they have cleared their path of any object even remotely comparable in size, for example Jupiter or Mercury. Our case is different and more like the Pluto-Charon case than the other planets because our moon is huge for a moon or maybe we (and Venus, Mars, etc.) should be in a different category from Saturn, Jupiter and other giants, after all we [Earth] are as different from an asteroid as they are from us. Planet is not a great word.
@@eleSDSU: Planet is an excellent word. Acting as if applying subcategories to something makes it no longer a part of the broader category as well is the problem (especially when subcategories already exist for the other 8: inner planets & gas giants!). All squares are rectangles; all dwarf planets are planets.
Of course, this means they've got a new answer coming soon. Something about the Moon not being formed from ejecta after all.
Wallace: “Everyone knows the Moon’s made of cheese.”
You've missed out my favourite one:
How many Earths does the moon have?
Rich Hall: Which moon are we talking about?!
At "The Earth orbits the Moon as well" you basically see Alan's brain break.
"In space no one can hear the claxon"
aww that last story was cute
Sandy is who we should all aspire to be like, she's just a delight
those last thirty seconds are incredible
I don’t get how why the moon suddenly becoming a planet makes the previous moons become irrelevant.
Pretty much all of this is QI bending or misinterpreting the actual definitions (in different ways) to make trick questions.
Cruithne does not orbit the Earth. It orbits the Sun but, due to Earth's gravitational influence, it takes roughly the same time as the Earth to do so, which makes it appear to behave as a moon, even though it isn't.
At any one time there may be thousands of small rocks in orbit around Earth. Those could be classed as moons as there is no formal limit for the minimum size of a moon. In practise only objects of at least ~1km diameter seem to be counted, which means the Earth only has one moon.
There definitely seems to be a misunderstanding of the "cleared its neighbourhood of smaller objects" criterion. It's about which object is gravitationally dominant. As to whether Earth qualifies, the Moon is held in orbit, objects such as Cruithne are held in resonant orbits (i.e. they orbit the Sun in the same time as Earth, or ratio thereof) due to Earth's influence, and any other nearby objects would either be quickly thrown away, collide with Earth, or be captured into an orbit or resonance, so Earth counts as a planet. It so dominates the Moon's gravity that to consider them binary planets (as argued here) is almost nonsensical. For systems such as Pluto/Charon, they are much closer in mass, so calling them a binary would make more sense. However they don't satisfy said criterion, so at best they would be binary dwarf planets.
There's no formal limit on where a system with two objects of similar mass are similar enough to be called a binary. One proposed idea is to look at whether the barycentre (centre of their orbits around each other) is inside the larger object or not, however that has problems as the distance between objects also affects that. Under that definition, Pluto and Charon would be a binary dwarf planet, Earth and Moon would be planet and moon, but the Sun and Jupiter would be a binary.
@@TheMoonRover Well it wouldn't be that weird to consider jupiter and the sun binary planets, if they were both planets..
There was one episode where Rich Hall re-appeared and had points deducted from an answer he gave in a previous appearance which was subsequently proven to be incorrect due to new evidence. I think it had something to do with either the moon or moons of one of the other planets.
Love that story by Sandi at the end
There is no TH sound in Irish. When you see a H, it means that the letter in front of it is silent. In fact, there used to be no Hs in Irish, right up to the invention of the typewriter. I silent letter used to be indicated by a dot above it but typewriters couldn't print the dot. So, they started indicating a silent letter by putting a H after it.
Thanks, that's going to be helpful from here out!
I LOVE the fact that this came out on the day that Israel crashed onto the moon. Unintentionally, but still, the irony is delicious.
To be fair, all moon landings have been controlled crashes :P
@@shanematthews1985 This one was a bit less controlled than normal. Oh well!!!
@@Kara1351 it's all about finding the best level of control, sometimes you hit and other times you really hit
