...or like saying Earth is not a planet because NEA's share our orbit.
If you have to argue that it doesn't apply to Jupiter or Earth because they are obviously planets, it implies that "clearing the neighbourhood" is a vague and not particularly useful criteria.
- drxzcl 1mo agoExcept I said nothing of the sort. I said the opposite. Jupiter, Neptune and earth in your example dominate the gravity of their orbit by locking the smaller bodies into orbital reasonances. It’s not a vague criterium. It might be an irrelevant one if you are interested in geophysics, but it’s concrete and testable.

- mr_toad 1mo agoIt’s not vague or unimportant. Clearing their orbits literally made them planets because they absorbed the mass of everything they cleared out.
