What effect would decreasing the distance between objects have on their gravitational attraction to each other?

Decreasing the distance between objects will result in a greater gravitational attraction between each other. This is because the distance is inversely related to the gravitational attraction. For instance, in the same way, if the distance between two objects was increased, then their gravitational attraction to each other would decrease.

Decreasing the distance between two objects having a considerable mass would increase the attraction on gravitation. The reverse is true that if you separate or inrease the objects distance would substantially decrease their gravitational attraction. Most object in our planet is held by its gravitational force towards it's center.
