Apparently Pluto was demoted based on the 3rd criteria:
3. has “cleared the neighbourhood” around its orbit.
But maybe Neptune should be demoted, after all, it didn’t “clear the neighborhood” of Pluto.
Pretty silly and arbitrary, I always thought they should set a diameter limit at Pluto’s diameter and classify anything equal or larger than that a planet.
This would give them a clear definition instead of a silly “cleared the neighborhood” criteria.
Yes, I wholeheartedly agree.
