The new definition is that for a body to qualify as a planet is that:

1. It must have enough gravity that it is round, or nearly so.
2. It must be the gravitationally dominant body in its orbital neighbourhood.

We ought to protest.

So how do we know that Earth is a planet then?
Who agreed the definition of a planet?
