Someone should make an astronomy shitpost site where the goal is to come up with a better definition of planet than the IAU, and people can vote on them and point out edge cases
today's bad definition: any object in space big enough to be visible by a telescope that's not actively undergoing fusion and isn't orbiting another planet (in which case it's a moon)
@foone Are structures partially made up of things undergoing fusion planets?
If no: Earth isn't a planet whenever someone is running their fusion reactor prototype. If yes: galaxies are planets (there's a lot of non fusing gas and dust in them)
