It would also effect the orbit of the sun about the earth.

If gravity was higher, we'd all be a lot more ripped!

I could do with a few years of increased gravitation pull, imo.

Forget the moon, how much extra mass would cause the Earth to slide out to an orbit that is too cold, or pulling away mass would push us into a killer hot orbit? Or do I have that backwards?

changing the mass of the earth wouldn't affect the orbit

Are you sure about that??? I'm pretty sure that it would affect the orbit. The mass of the earth changing would mean that the pull on the moon would change, which would cause the orbit to change. Right???
