Can we please define what the fuck is a planet already. /Sci/ please give me a definition of a planet so we can end future "is x a planet" debates. to me, a planet is an object with enough mass to become a sphere. i know that definition has a lot of flaws, but it can be expanded upon, which is the purpose of this thread. either expand upon my definition, or propose your own. either way we aint leaving til we have a real definition.
