As the Force of friction is equal to 
µ
by using the Law of Action Reaction; as the force normal is the conterforce of gravity
µ
µ
Therefore, by looking at the equation we can infer that
The force of friction is directly proportional to the mass, gravitational constant, and the co-efficent of friction
Because the gravitational constant is dependant on gravitation, a planet's mass and radius also affect the force of friction
But DO NOTE:
That the co-effecient of friction is only applicable between two rubbing surfaces and unaffected by gravitational constants.
