Gravitational pull is determined by
-the sun and stars
-acceleration and volume
-volume and mass
-mass and distance

The gravitational pull is determined by the mass and distance.

Explanation:

According to Newton's law of universal gravitation

where F is the gravitational pull, G is gravitational constant, m₁ and m₂ are masses of bodies and r is the distance between them.

It can be seen from the above equation that F is directly proportional to the product of the masses and inversely proportional to the square of distance between them.

                      F ∝ m₁m₂

                      F ∝ 1/r²
