Presumably that it’s now considered a dwarf planet and that there are multiple other d. planets in the system, of similar size such as Haumea (minor-planet number 136108), Eris, etc.
replyThe dwarf planet is just a naming thing. I don't know if beyond oluto bodies are a new or recent thing. I was thinking someone discovered something completely different like totally new findings about its geology or something like that.
replyPluto is Mickey Mouse's pet and is not anthropomorhic. Not to be confused with Goofy that is an anthropomorphic dog and Mickey's friend.
replyAnd Minnie is a mouse and has a cat as a pet, Figaro.
replyHere's the funny thing about cartoons and confusion. In the comic Popeye the antagonist is named "Bluto" but only sometimes. He was renamed as "Brutus" because of a misunderstanding of rights ownership.

However, because it was a misunderstanding, his "Bluto" moniker was later restored, and even retconned as the name of twin brothers.
Popeye has never been a Disney property. But the funny thing is that my father told me that they renamed "Bluto" so that he wasn't phonetically confused with "Pluto", who is obviously a different character in a different property. And that premise is the one that I grew up believing, until Wikipedia was invented.
