The force of gravity is inversely proportional to the distance between them, so the further the distance, the weaker the gravitational attraction. This is an inverse square law, so the force decreases by 1/distance squared

Thinking strictly newtonian
F = [G M1 M2]/ d^2
F = Force of attraction between two bodies
G = universal gravitational constant
M1 = mass of body 1
M2 = mass of body 2
d = distance [sometimes r is used in this equation since it represents the distance between the exact centers of the two bodies--not distance from the surafces.]
This is also referred to the inverse square law of gravity. The farther apart two objects are, the less [proportionally] their gravitational attraction to each other is. Double the distance, attraction weakens 4 times, triple it then 9 times.

we did this last year in physics. heres a diagram of what we looked at.
O-------------------------) weaker
O---------) stronger
the further something is away from a gravitational center, the weaker the gravitational pull is.
