There is an equation for this, and it will help us answer the question:
F = G × m₁*m₂ ÷ r²
The question already tells us the force of gravity between two objects depends on the objects' mass. Now we have to find a second factor.
Their shapes are not a secondary factor to this question.
What they are made of is not a factor to the gravitational force between the two.
Their weights have nothing to do with this either.
However, the distance does. According to the equation
F = G × m₁*m₂ ÷ r²
r² is the radius, or in other words, the distance between the two masses from their center of gravity. Therefore the distance and masses of two objects are what affect the gravitational pull between the two.
Have a nice day!
