I didn't think gravity had anything to do with density. Isn't the gravitational formula unrelated to density? I think it's something like ((M1 * M2)/D^2)*G; where the Ms are the masses of the objects in question, D is the distance between them, and G is the gravitational constant. Whether you stretch out Earth to be the size of Jupiter or you shrink it down to the size of a pinhead, gravity wouldn't change, according to this formula. Is this formula too old-school/obsolete?

Does density play a part in gravity?
