Re: Does more mass change orbits (Bill Gill)

This is the problem with gravity. Would the overall effect still lead to the moon orbiting the earth in 28 days. It would have to or else a heavier object would fall faster that a light one in a gravity field. Put simply, all objects fall at the same speed, heavy or light in a gravity field, so if the moon was heavier it would still fall at the same speed and would still orbit the earth in 28 days. The fact that the earth and moon would move differently to achieve the same end result leads to the ideal that the mass of an object doesen't change the pull of gravity but how they move around each other.
