    Either Pluto is not a planet, or we live in a solar system with 200-1000 planets.

    So either 8 or +200, but it will never be 9 again.

      Pick a size. Get away from judgement calls. This big or bigger is a planet. Smaller is not. Done.

      No weird rules. Make it a diameter of 2000 km. That’s no more random than anything else. So we’d have 10 planets, with Eris and Pluto being the new ones. NO BIG DEAL. It’s measurable. We see something new, we know what to do with it. None of this dwarf planet thing, which isn’t a thing btw. We already had planetoids. Renaming for renaming’s sake. It even sounds like the IAU isn’t sure or unified about this.
