Orbiting bodies in the star system at Sigma Draconis.
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, gas clouds and comets, which are all held in place in the star's gravity.
History and specifics[]
A multiple star system exists when more than one star are locked together by gravitational attraction. As such, a system with two stars is called a binary star system, and three stars form a trinary star system.
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)
