A half century ago I was taught that Pluto was a real planet. A real honest to gosh heavenly body of orbital persuasion. Lies all lies! The truth is finally out. Pluto doesn't even have enough mass to be round. Even our Earth's lowly moon can pass that test. So out it goes, Cast into the Dustbin of History.
All joking aside, the International Astronomical Union's, secret committee intent on elevating many more planettes to planet status must have been dredged up from scientist wannabes. What were they thinking! (We might need a new definition of thinking.) It's revealing that more than 95% of the astronomers didn't take part in the voting for a definition of a planet. A definition, it should be noted, that is limited to planets in our solar system.
