      Unfortunately, Pluto was a victim of how hard it is/was for us to detect planets and other objects at that distance. It was the first one we saw for a while, but once we got a clearer picture, there was no way we could keep calling it a planet.

          But then why isn‘t Ceres also a Planet? Or Eris? Or Quaoar? Or any of the other objects classified as dwarf planets

          The answer is easy: Besides their size, they all behave very differently from the actual Planets. Doesn’t mean they’re any less important, they’re just something slightly different.
