It depends only on the weight of the bodies and the distance between them this is the simplest explanation. Law of Gravitation or Law of Universal Gravitation by Newton states that Every object in this universe is attracting every other object towards it with a force called the gravitational force of attraction. The universal gravitational constant is used in Newtons Universal Law of Gravitation Einsteins General Theory of Relativity and also Keplers Third Law of Planetary Motion to calculate the time period of a planet to complete one full revolution in its orbit.
This is known as Newtons law of universal gravitation.

According to the universal law of gravitation all material bodies attract each other while the attractive force does not depend on the physical or chemical properties of the bodies. Every particle attracts every other particle in the universe with a force which is directly proportional to the. To know about the history of gravitation watch this video 378302.
