WebBig objects are also attracted to smaller ones; their centres of gravity combine into one system. So the centre of gravity for the earth is in its centre. But the centre of gravity for the earth/moon system is about below the surface of the earth, as it combines the gravitational forces of both bodies. http://www.actforlibraries.org/how-gravity-actually-works/
