I don't agree with this; "so you can still say the moon orbits the planet."

No, both the moon and planet orbit the barycenter. The Earth rotates around its barycenter, as does our moon. The Moon does not really orbit the Earth. It orbits the barycenter.

I can tell, this is going to get fun.

My 2 cents.
