>>20963170I wonder why OP left out Charon
Because the Pluto/Charon system has its barycenter outside of Pluto's radius
Mostly people like OP just don't understand that words can have different meanings in different contexts, especially specialized fields
You can call anything a planet if you want, but when you're talking to astrophysicists, the word has a definite meaning
Just like saying "level" means something different to a surveyor than it does to most people
