@georgia Crafting of definitions are based on usage, we dont get to pick and choose what a definition is for existing words.

Planet was never a technical term, it was archaic, so they had no right to try to redefine it contrary to its usage. If they wanted a technical term then they should have made up a new term for what they wanted.

Thats the whole point, you dont get the right to craft definitions for words already in common use, the usage dictates the definition not the other way around.
