I think it’s kind of cute that Mike Brown waited with his announcement of Quaoar so it would get the number 50 000. Twenty years ago you could do that, but today when we discover several every day that’s not really possible. Thanks Nick. We were going to watch the comet tonight, but it’s overcast. Hopefully it will clear later tonight.

3:20 - Tiny correction: The near edge of an object ALWAYS feels more gravity than the far edge, but above the Roche Limit, the difference in gravity isn't strong enough to pull apart a loose conglomeration such as a gravel-pile asteroid. Below the Roche Limit, the difference in gravity _is_ enough to start pulling pebbles off the gravel-pile. (if the object is a single fused piece, the Roche Limit is no longer a death sentence for it, hence why the International Space Station doesn't tear to pieces.)
The outer solar system remains my favorite astronomy topic I'd sooner point all telescopes we have on that region of space then look for things billions upon billions of lightyears away, or hunt for exoplanets we will probably never visit anyway. Not in our lifetime at least. But the idea that this close to Earth exists a vast wealth of untapped and even unknown worlds, let alone maybe Planet 9, I find that very fascinating. Thanks for yet another video on this topic.
It all comes down to binding energy of the progenitor. Gravitational self-attraction, crystalline bond strength for rocks or ices, rotation of the progenitor. All the things that make up how strong an object is when it falls past the Roche limit. More weakly bound bodies will fracture sooner than stronger bodies (i.e. rubble piles vs metal asteroids). For binary stars this is hydrostatic equilibrium.
Let me add to this in noting that Quaoar might have a less massive binary companion that was only weakly-bound to it in addition to its primordial moon which was broken up early on. When this companion departed after, it pull the moon's remnants outwards to another stable configuration well beyond the Roche limit
One day, once we’ve learned the necessary lessons and outgrown the petty stupidity of the “modern era” through all that may cost, humans will actually see these sights and aim to be something greater.
Bleak dude! But yeah, we as a species have a ton of things to work out between now and then. Thanks to Nick for keeping the lights burning through the darkness.
@mendelovitch do you really need to ask? Bless this channel, and all the others like Isaac Arthur, JMG and co for reminding us that there is something greater and awesome to aspire to!
It’ll be interesting to see how much the Sun has actually orbiting it. Could it be that single star systems are more stable and able to hold more objects in it’s periphery, or is it because of the mass of the sun? If it’s the mass then one has to imagine how many bodies are in orbit around massive stars. I also get the feeling interstellar space is much more cluttered than we once believed, especially in the disc of the galaxy.

This is all just speculation, but larger stars and binary systems could also have less planets if they leave the proto solar system with less material for planet formation. For example, more of the material could be locked up in the stars, or the larger solar mass could result in a stronger solar wind which could blow more of the material out of the solar system before it has had a chance to clump together.
Obviously, this is the debris from when the Plutonians defeated the rebel fleet, which incidentally happened in the past 30 years but not when we were looking. ... Or maybe the Orcusians; I think we'd've noticed by now if Pluto were sending out warships.
We in the Federation of Sol need to be united. The Emirates of Hacan is plotting together with the Necro Virus. We can not trust anyone across the Galaxy.
Nick, I'm a long-time viewer of your channel, and there was an update to the Quaoar story from a couple weeks back. No one seems to have mentioned it in the comments, so I wanted to make sure you were aware; there was another occultation of Quaoar, and they found a second ring, inwards of the first, but still beyond the Roche Limit. It seems Quaoar's rotation and Weywot's orbital period are able to create several stable regions, it's likely we've only found the two thickest of a bizarre lattice work of rings! It's a very exciting discovery for the Kuiper Belt!
There's a Centaur out around the orbits of Saturn or further out maybe that also has a ring; if not an asteroid ring. I can't wait to see these things!(maybe - I'm 47)
It's so exiting that we are finally able to find things like these... with how precisely we can predict stellar occultations now thanks to GAIA hopefully observations of KBOs become more common
Just like that, what we thought we knew may not be. New science is always a good day, especially for a young astronomer. Congrats to Mr. Morgado and team.
Angular momentum and orbital mechanics might not be as simple as we think. Maybe Dark matter is just a unrecognized effect of orbital mechanics and angular momentum. Something a keen to Tesla's scalar field in electromagnetism.
@@parallaxnick637 oic, I stand corrected! Still my favorite ;) Still, at the time of its discovery, it was the most bizarre solar system body, even if similar ones have been found since
Well I'm not going to debate dp or pl. Definition but I will say this i support the proposed new def. By the planetary scientists pl. Should be determined based on geophysical properties and not based on gravity and orbit. Or a number of pls. Should be. A Pl. Should be based on the topagraphy in what makes a planet a planet regardless of their orbit... but I would say this i c it as they are a pl.
It’s always so nice to hear someone else who agrees! 👍🏻 I never understood defining planets by location or orbit, as we never do that anywhere in astronomy (or science, for that matter). Although, this “new” geophysical definition isn’t new. It’s been used by planetary scientists since 2006 when the IAU made their mistake. Since planetary scientists study these objects for a living, THEY decide what a planet is. So logically, Quaoar has always been a planet. An unscientific, uneducated, underhanded, illegitimate, idiotic, politically-driven vote will never change that. And yes, dwarf planets ARE planets!

If they find another moon here, they should name it Fahrqouar

If it has very large components up to 1km in diameter, could they be acting as "shepherd moons"?
very possible.
