I propose a better definition:

Planets are very large objects orbitting a star that dwarf everything nearby

I'm pretty sure this is the intent of the IAU's definition. It's just more specific.

Ah, yes. "very large", "dwarf everything", and "nearby" are very specific terms...

Yes, that is why I mentioned the IAU's definition was more specific.

Very large? Enough mass to have a round shape.

Dwarf everything nearby? Clear out its orbit by colliding with/capturing/ejecting shit.
