Mass and Distance
The mass of the objects and the distance between the objects.
Gravity is proportional to mass and inversely proportional to the square of the distance between the two bodies.
Gravitational forces depend on the masses of the objects involved and the distance between them. The force of gravity increases with the mass of the objects and decreases with the distance between them.
The masses (both of them), and the distance.

The 2 masses and the distance between them.
The amount of gravitational force between two objects depends on their masses and the distance between them. The force increases with the mass of the objects and decreases as the distance between them increases.
Heat depends on the temperature difference between two objects and the thermal conductivity of the materials involved.
The force of gravity between objects depends on their masses and the distance between their centers. The force of gravity increases with the mass of the objects and decreases as the distance between them increases.
Thing #1). The product of the masses of the two objects. (You don't have to know the individual masses, only their product.) Thing #2). The distance between the centers of mass of the two objects.
