    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?

        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.

        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.

        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.
