Actually interestingly enough gravity is not really a force between masses as most will have you belive but is due to the curvature of space that is caused by the masses. The Sun is so huge that is curves space and that is why the planets orbit instead of slamming into eachother. They follow the path of space which is curved. The further away the more parallel space is and less curved the path. Also Earth is large enough to curve space too and objects dropped are just traveling along the curved space created by the masive earth.
