A star system is an area of space located around a star, and includes all of the objects that orbit that star, i.e. planets, moons, asteroids, and comets, which are all held in place in the star's gravity well.
The size of a solar system is usually dictated by the extent of a star's gravitational pull on the system. The edge of a system is usually made up of an Oort cloud, which is a layer of ice and debris. (ST reference: Star Charts)
