I don't understand it anymore than I entirely understand your post! 😵💫

I agree! Like you should have made up your mind sooner instead of making the curriculum teach it's a planet only to have to reteach students that it isn't!

Something to do with it's size. Since there are other things bigger than Pluto they thought it was easier to downgrade it rather than declaring new planets.

Easy, its so far away they thought that it had more mass than was there. Technology advanced and the images that showed the planetary body in the first place was inaccurate. Its more of a belt of gargantuan space rocks.
