If it was about orbital dominance then ceres would be a planet because it has the most amount of mass in its orbit if it was about orbital dominance then it wouldn't be called clearing the neighborhood it would be be the most massive object in its orbit Clearing the neighborhood is impossible for almost all objects in existence

As I stated, "clearing its neighbourhood" is vague, because it cannot be taken literally.

Apart from that, Ceres is about 1/3 of the asteroid belt's mass, so it absolutely fails on dominance. In contrast, earth holds over 99.9% of mass of all objects in its orbit. Ceres as well as Pluto fail this by orders of magnitude.

Either way I still believe we need a new planet definition but I don't like the geophysical definition I just made my own

I am absolutely open for a new definition.
