2     It is; it isn't. It is, but with some restrictions. No, it isn't. Yes, it is, sort of. These are the arguments about poor Pluto. Is it a planet, or isn't it?

Secondly, it must be big enough for gravity to make it into a round ball. And lastly, it must have cleared out its orbital neighborhood. There can't be any "junk" floating around it.
