Yes, at infinity separation, the gravitational attraction between two objects is zero. You typically measure the force of gravity between two objects by measuring the distance between their center of masses, and then treating them like they're point particles with mass at that point. For two obejcts, the force of gravity between them is: f = G* m1* m2/r2. Where G is Newton's constant, m1 and m2 are the masses and r is the distance between their center of masses. So if you put a point between two objects where the force from one is equal to the force from another they would cancel.
