Another one bites the cosmic dust

Always "Pluto, Pluto, Pluto". Why does no one ever remember Ceres, Eris, Haumea, and Makemake? They're each as much of a "planet" as Pluto is.
- Meanwhile I'm more focused on the "invisible 9th planet"
  There's apparently some gravitational data that says there should be a 9th planet in between Jupiter and Saturn* that we've simply been unable to physical observe.
  *I don't remember the actual placement
  
  I thought we figured out why the calculations were off and it wasn't actually because of an unknown body out yonder? Is there new evidence or am i just misremembering stuff?
  
  Honestly I haven't researched it in a while so that's entirely possible and I'm just outdated
  
  The theory I've heard is that the Oort Cloud is more massive than previously thought, and that said mass might represent Planet IX.
  
  Just like the simulations
  
  We've had "hidden" planets multiple times actually. In one case, we discovered Neptune by observing that Uranus' orbit was wonky, and this really Bolstered peoples' trust of Newton's gravitational theory.
  The existence of another planet even closer to the sun than Mercury, Vulcan, was also hypothesized by the same astronomer who predicted Neptune's existence. This was due to Mercury also having a wonky orbit. After Einstein's general relativity came about though, it was found that no new planet was necessary to explain Mercury's orbit.
  I think this new planet is the one predicted by Cal Tech "Planet Nine", is supposedly 10 Earths in size, orbits on average 20 times further out than Neptune, and has a very oblong orbit out in deep space.
  As another 'fun' tangent, there is some debate every now and again that dark matter may demonstrate that Einstein's Theory of Relativity is also flawed and that we're in need of a new theory. Currently, though, there has not been a sufficient new theory to take its place, so the existence of 'unseen' matter still is the strongest explanation we have. I put 'fun' in quotes because it seems like this debate is starting to affect astronomers and physicists the same way that 'The Orangutan" affects Edgar Allen Poe experts. Video related
  
  If astronomers named Vulcan before we ever saw it, then let's name planet 9 already. I propose either Erebus (darkness) or Letum (death)
  
  The Poe rabbit hole was well worth the read. Thank you
  
  Angela Collier actually goes a little more in depth in that video on why MOND is unlikely, even though she does admit it hasn't been fully ruled out. I didn't get the impression physicists don't talk about it because it causes debates, which she claimed seems to happen more often on the internet. I got the impression that most physicists just think it is unlikely to go anywhere, so they just aren't as interested in it.
  
  What's mond
  
  Modified Newtonian Dynamics
  
  It was killed as a theory very recently so yeah
  
  The proposed 9th planet is beyond Sedna and is hypothesized because Kuiper belt objects are orbiting strangely to they figure a gravitational influence from further out is causing it. Uranus was seen doing the same thing and that's how Neptune was confirmed found.
  
  Wasn't it supposed to be way the hell off of the orbital plane? I can't find anything searching for it now but I swear I remember they thought its orbit would be weird compared to the other planets.
  
  Most trans-neptunian objects do there's no reason to believe this one doesn't.
  
  Imposible. Perhaps the archives are incomplete
  
  between Jupiter and Saturn* that we’ve simply been unable to physical observe.
  *I don’t remember the actual placement
  If it were as close as Saturn, we'd be able to easily see it. If additional planets exist, they would be beyond Neptune, and likely quite far beyond it.
  
  Yeah like I said to the other commentor. My info is outdated as i haven't really looked into it in a while.
  
  I've been looking forward to this
  
  Do you have a link for that? Pluto is tiny and much farther away and we can easily see it. There's no reason I can think of why we couldn't see a planet in that orbit, even a small one.
  
  We definitely have the telescopes to find it now if it exists, so I'd say it doesn't exist. What if it's a tiny black hole? Maybe it's a wormhole to Alpha Centauri!
  
  It's theorised to be on an elliptic, off plane orbit. We currently lack the telescopes to do a true sweep of the skies, at the resolution needed to find it. If we know where to look, it's easy. However, we don't know where to look right now.
  
  Oh I have a bad feeling about this
- Ceres was thought to be a planet as well. Better telescopes got it demoted.
  
  Wait a minute, how did this happen? we're smarter than this!
  
  Are all of your comments Star Wars quotes?
  
  It's a trick. Send no reply. Send no transmissions of any kind.
  
  Looks like all their comments on this community are, anyway. Their other comments are normal.
  
  ... Possibly
- They're all black
  
  My Lord, is that legal?
  I'll make it legal
