Oh man this was me! I 100% agreed until I saw relative size of Pluto[0].
Definitely seems unfair to call it a planet when there's a number of Kuiper belt objects that are larger[1](?) or pretty much the same size.

- Robotbeat 5y agoPlanetary scientists tend to consider Pluto, and those large Kuiper Belt Objects, to be “planets.” It’s just certain astronomers, who don’t usually study planets, who voted to remove them from planethood. https://www.ucf.edu/news/pluto-planet-research/?amp https://www.ucf.edu/news/pluto-planet-research/?amp Pluto is an impressive planetary system with a bunch of Moons and active geology. I’m gonna call it a planet. Also kind of funny, but this guy who is obsessed with finding “Planet 9” (which doesn’t seem to exist) is also the one who tried and succeeded at demoting Pluto.
- jjk166 5y agoPluto is closer in size to Earth than Earth is to Jupiter, but we lump them both into the same category. There was a real concern that we were going to find thousands of Pluto sized objects in the kuiper belt, and that when we observed them up close they were just going to look like big comets. Instead it turns out there are only a handful and they are fascinating worlds with many similarities to other planets.
