Pluto was always bullshit. it was clearly an outsider, and it’s shares characteristics with tons of other bodies in the system. so is Pluto is a planet then the solar system has numerous planets and there’s barely any point in knowing about them at that point.

tbh i think the only reason it was even “important” was because it was the only one discovered by an American. also it was predicted because of a faulty calculation of mass of Neptune, so it was a lucky guess more than an actual informed prediction.
