This hypothesized ninth planet (not you, sorry Pluto) might explain the unusual commonalities of extreme trans-Neptunian objects (ETNOs) 100s of AU from the sun. These ETNOs (such as dwarf planets and sednoids) have remarkably aligned orbits, suggest the existence of an undiscovered celestial body, dubbed Planet Nine, influencing them gravitationally.

    Back in my day is was called Planet X. Sad

    Pluto will always be the ninth planet in my book.

      Even if it’s a dwarf planet, it’s still a planet. It’s right there in the name: dwarf planet.

      This article should be about “Planet 18” since Wikipedia recognizes 17 planets already.

      I prefer to think of Pluto as the king of the dwarf planets and namesake of the Plutoids, rather than as a weird lesser planet not appreciably bigger than its moon.

        I see Pluto and Charon as Irish twins. Or at least 2 under 2. I somehow always imagine two siblings spinning around each other. Maybe Pluto is showing a 🫶 to his little sister.

      It can’t be the ninth planet. It literally can’t. It’s either not a planet, or its the tenth planet.

          Exactly! Fair enough if you want to define a planet as “anything big enough to be rounded by self-gravity, but too small to undergo fusion in its core.” But there is no definition of a planet, (or at least one without an arbitrary rule like "planets have to be X km in diameter,) that allows Pluto to be a planet without Ceres also being a planet.

      Yeah, I have a lot of outdated books too.

      Edit: I guess people don’t enjoy book puns?

    There’s the even more hypothetical and highly theoretical Planet Eleven. It’s so obscure there aren’t even rumors about it.

    Potentially stupid question: Granted that we have such good vision for planets an incomprehensible distance away from us, why wouldn’t we be able to detect, with certainty, if this planet is actually present in our system? I’m guessing it would take longer to orbit around the sun, than Pluto’s 247 years, but it’d still be detectable because of the distance away from us

      The problem is the potential planet is so far that it would barely reflect any light. We have inferred from computer models that for known planet and object orbits in our neck of the woods, there needs to be a planet there to create those orbits.

      We just can’t see it because it’s so far out there, it’s really really dark, and it doesn’t pass in front of a star to see the dimming effect that would let us know it’s there. If we knew where to exactly point telescopes, it’s possible with enough study we could say it’s really there.

        That makes sense. Thanks for the answer!

      Not a stupid question.

      Beyond the too far to reflect light aspect, the evidence we do have is gravitational effects to other bodies we can see and track. So there is evidence that something is out there. It’s just a matter of what and exactly where.

    Nibiru who come around every few thousand years so the ( i think reptilian ) that live on it can harvest our gold ans human for slavery

    It’s a nice rabbit hole to follow
