From Wikipedia: "An astronomical body's Hill sphere is the region in which it dominates the attraction of satellites." In other words, any object (such as a star, or a small galaxy) within a galaxy's Hill sphere can have a stable orbit; the orbit of anything outside of such a Hill sphere will eventually decay; in other words, it might escape, or fall towards the galaxy.
