The god of the dead and the ferryman for the dead being kissing cousins makes perfect sense. But, seriously, thanks for sharing an intriguing look at planetary (or, dwarf-planetary) evolution. It's fascinating to see people working out these hypotheses.
Kiss and capture cannot have applied to the earth moon formation. If the earth were barely grazed by a large mar size object, it wouldn’t create enough debris and the debris ring would be inside the Roche radius and would fall back down to earth leaving no moon.
I have a theory that Earth might have been a binary planet with Venus, and such a kiss stopped Venus rotation and sent Earth to its current orbit with the moon chunk
It was an electrical event. Birkeland currents create a Z-pinch at a planetary bodies center, and discharge mass to the opposite poles. Effectively cutting it in half. Also why two planetary bodies can accrete from the same mass, and have a dichotomy of elements. Like the moon and earth.
Metaphor from ancient observation ? Charon ferried the living mortals Heracles and Aeneas to the underworld and back again. Pluto has a very cold heart.
The problem with simulations like these is that initial assumptions tend to be extremely unlikely. Going back to the initial cloud of dust, the likely scenario is that the eventual bodies shared a common swirl, or eddy, that made that portion of the cloud unique. Billions of years of evolution make things converge on zones of initial order; it does not favor the randomness used in simulations.
Wouldn't these objects have touched only briefly? The collision likely slowed down Charon enough to be captured by Pluto, but it seems unlikely they would form a peanut-like planet for long, as there isn't a straightforward way for the system to gain angular momentum to make them fly apart again. At the moment, the angular momentum of the Pluto-Charon system is probably slowly decreasing, as some of it will get transferred to the tiny outer satellites. So, in the past, Pluto and Charon may have been further apart.
Anton. it's very simple. Indeed the universe is electrical in nature. The is a welding type interaction between two oppositely charge bodies of nearly the same amount of potential. Where there is massive difference in charge there is more of a ripping of material as one sees on Mars, the Moon and thew western US mountains.
As they say in programing. Garbage in, garbage out. By what reasoning are they assuming a lower impact velocity? Is there a speed limit posted in the out solar system they didn't tell us about?
They were probably moons of a larger planet like jupiter. With orbits close enough to each other that eventually drug each other out of jupiters orbit, flinging them to the edge of the solar system. The other small satelites were probably also captured during their exodus.
I’ve always been curious, with how delicate the balance is between Pluto and Charon, how large of an object would be required to disturb said balance via a passby?
wow cool. So ok, I have a few theories. One you mentioned already. Say the two bodies kissed and were stuck together then some other object smacked into that busting it off. OR... Perhaps the touch and kiss movement sped up the rotation of Pluto and in time that rotation was enough to throw off the kissing object. And yea, I'm sure either way the impact itself threw off enough stuff to form the other moons. OR those other moons came along when the two first kissed. Could the combined gravity of both be enough to capture some local junk at the time? I'm sure they are working on all this, I just like to wonder.
Imagine the funky gravity if you were standing near the contract point of the kissing objects. I understand perfectly how those small snowmen happen, but I just can't wrap my head around how Pluto&Charon didn't combine. They're both big enough to form into spheres from their gravity, so how didn't that happen when they were basically one object? I can imagine what happened, like how you described, but my brain just won't accept it. Used to be you'd get a mind bending discovery once a decade at best, but now it's every month (or even week) that something unexplained is found!
@@VikingTeddy Maybe they just bumped each other and maybe just that slowed down someones movement enough to let gravity keep them going around each other. Yea it could be that. Sure. lol.
@@Mephistahpheles And stuff that hasn't happened yet might be happening now for the first time. It could happen. Or be happening. Or will be happening in some later happenstance. lol. Ok I'll stop now.
Just went forward and did a sim. Seems so terrestrial planets were once a massive singular planet that was ripped apart by a passing massive gravitational object (very possibly a brown dwarf). This also explains the orbits of the gas giants without our planet 9.
Did the scientists think the reason the two objects gained enough energy to separate again was because of the YORP effect? If so, i would find that surprising, since the energy for it is usually very low, if not, where did the energy for later separation come from?
I'm not ready to accept the collision hypothesis as presented. Firstly because the distances in this region of space are so huge and secondly it is assumed that there is the captor and the captive when both objects have gravitational attraction in a region that is extremely sparsely populated. There are too many assumptions here. What a shame that so little information was gathered by so brief a fly by.
As the collision occurred, the frozen gas exploded under the impact zone. This explosion separated the two objects and left the heart shaped plane behind.
Perhaps it is time to change the name of the micro planet from Pluto to Hades. It has that heart shaped mark. And now this kiss and capture theory. But then we'd have to rename Charon to Persephone, the daughter of Demeter.
I would call it a Kuiper Peanut. One lobe larger, one smaller? Then they separate Into a Pluto Cheron Orbit if they're massive enough? Is that the deal?
I am having trouble visualizing the process by which our hot and soupy planetary neighborhood became the cooler geology and the rocky fabulous wealth we now observe and enjoy. Like, how did the gold and platinum and lithium get here, created by crazily distant incredible explosions? And I wonder about how various ores sorts themselves out in the cooling phases ... Darn. Again, I wish I'd studied geology. D'oh.
Huh, never heard Charon pronounced that way before. Now I wonder which is right, I give the Ch a k sound. I wonder, as Pluto can go inside of Neptune's orbit, if there is a chance they will ever collide.
Kuiper belt objects that get close to Neptune's orbit, including Pluto, are "synchronized" with Neptune, so they don't have close encounters. The ones that weren't have had their orbits destabilized or were flung off into the void over the course of billions of years.
No. Pluto and Neptune are in a 3:2 orbital resonance, so they can never collide. Edit: Pluto's orbit is also inclined approx. 17 degrees with respect to Neptune's orbit, providing another layer of collision avoidance.
Sounds like pluto (etc) is in the process of becoming a planet. If/when something gets close enough to Pluto/Charon to be captured, the process could accelerate. Pluto might have to get another designation change. 🙂
I have no faith in the theory for objects larger than perhaps a few tens of miles in size. The angular momentum of objects the size of Pluto and Charon is enormous, further the Roche Limit would be an issue as Pluto would start to pull Charon apart. We may not understand how they came about just year, but I have no faith in this.
Don't need faith. The simulations (which are just extensive calculations) demonstrate that it isn't just possible.....it's likely. Of course, it's certainly possible there are mistakes. Skepticism is good. So....go study it, and find the problem....or convince yourself of it's validity. Or, maybe science is just religion to you. Have (or don't have) faith in whomever. 🙂
@@Mephistahpheles I spent years running simulation of impacts of object from asteroids to planets - no object over 50km the roche limit came into play and the objects started to break up before impact, invariably forming a ring like structure which then slowly rains down on the larger body or gets ejected out of the system. The chances of object of the size of Pluto and Charon coming together so "gently" that phsyics took a back seat is no different, in my humble opinion, to believing in God. The difference is, further simulations with soon prove this to be incorrect.
Today's astronomers must feel right at home with Roblox-the pixelated images they share look oddly familiar. The formation of planets seems more likely to have been influenced, or collisions, occurred by objects with comet-like orbits, featuring larger orbital paths and different angles relative to our solar system.
I like the thea/moon idea, could imagine a collision such as that could have perhaps produced the chunk of rock that eventually destroyed the dinosaurs rather than a kuiper belt object or rogue body.
The composition of the asteroid differed from Earth's. That was part of how an impact event was initially discovered; by seeing a layer of composition that came from somewhere else.
@WaterShowsProd more than likely, not to say that bodies with certain elements that existed in our solar system that are rarer didn't , early in the formation . Lost to the sun , scattered fragments or pushed out by solar wind which i suppose would been much stronger in a younger system and chaotic.
@@neilhallberg1784 By "somewhere else" I just meant not originating on Earth, I didn't mean to imply that it came from outside the solar system. Different areas of the solar system are richer in different elements.
at 3:40 in this video, there's an (inverted) image of the "Nova Scotia" peninisula, used elsewhere, Isaac Arthur used it too. but yeah point being that it's inverted from reality. it should be pointing East, not West.
Heh. Good eye! Reminds me of my dad: a lithographer that was always testing me with "spot what's wrong" things in pictures (and why). He regularly presented me pictures and asked me, "What's wrong with this?"
Since the definition of a planet was redefined, I feel like a "moon" should get redefined too. To me, and Moon has to be large enough to be an oblate sphere and clear its orbit like a planet does. Everything else should just be called a (natural) satellite. Lets start a campaign with the AU. lol.
Eventually the Earth and the moon will be totally locked technically wear a double planet now. The systems just slowing down to equalize the angular momentum
Not a bad idea. It would mean phobos & diemos might get demoted. Likely lots of the little chunks orbitting Saturn & Jupiter, too. Still, I like the idea. A moon SHOULD be moon-ish.
@@Flesh_Wizard Yup....twin planet, moonlet, dwarf moon....all reasonable ideas. Considering the # of things orbiting planets has grown so much, it'd make a lot of sense to start categorizing them.

@@spinnetti to follow along with this whole conversation I definitely agree that a Moon should be able to at least clear out its orbital feild. I don't think they need to be perfectly round but I do think that should be a thing

Some additional source of energy is needed, thus complicating their hypothesis. Also left unexplained is how the other moons in the Pluto-Charon system formed, which seems to me to need even more energy to explain. This hypothesis looks like it needs more work.
2:42 What do you mean by capture 'directly'? You'd always need to get rid of the excess angular momentum, either by interaction with (and ejection) of a third body or through an impact.

Interesting hypothesis. Can't wait for Vera Rubin to come online so that we can learn of more.
They need to look for regions on both that have similar terrain from when they were joined.
They both have large flat Plains with few features that are about the right size. That's some of the supporting data for this idea

Imagine standing on an almost contact binary planet when its partner passes over.
Except in that case, both planets would be tidally locked to each other and the partner would remain almost perfectly stationary in the sky.
