The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
mass and distance (between two objects) are those TWO things that affect the gravitational force acting on an object
The gravitational force acting on an object is affected by two factors: the mass of the objects involved and the distance between them. Greater mass results in greater force, while increasing distance results in a weaker gravitational attraction. This relationship is described by Newton's law of universal gravitation.
