Description : When two objects are near each other how would increasing one object's mass affect the other object?
Last Answer : The other object would be drawn more strongly to the one with increased mass. But whether that influenced their motion would depend on the actual forces involved. Since gravity is a "mutual" attraction, the effect on the two-object system could vary in ways other than the increased net attraction.
