Newtons Law of Gravitation says that the planets, the stars , and the Sun all exert the force of gravity.
Newton's Laws
Newton's 1st Law
An object in motion tends to stay in motion and an object at rest tends to stay in rest unless acted upon by an outside force.
Newton's 2nd Law
An object's acceleration is dependent upon the mass and the force acting on it.
Newton's 3rd Law
Every action has an equal and opposite reaction.
Mass
Measured by the amount of matter an object has. Though your weight changes with the force of gravity your mass does not.
