Hey, if we find something bigger than Pluto, then by all means let’s call it a planet.

By any reasonable person’s definition of a planet, Pluto is a planet. It’s a rocky spherical mass that orbits the sun, with a varied terrain of mountains, plains and glaciers. It has days and seasons. It has its own system of moons.

Additionally, bythe IAU’s stupid definition of a Dwarf Planet, Charon should really be called a dwarf planet too. It isn’t a satellite in a meaningful sense - both Pluto and Charon orbit a point between them. The other moons also orbit this space between Charon and Pluto.

Want to know why it isn’t? Because the IAU class it as a planetary satellite. What’s the formal definition of a planetary satellite then? There isn’t one. It was discussed, but a formal definition was not decided upon. Charon is literally a moon now because it was called a moon before the definition of a planet was changed.

I’m all for formal definitions, but the IAUs current rules are just really sloppy. It’s maddening.
