- Binary star - WikipediaA binary star or binary star system is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called visual binaries.
- Types of Binary Stars - Australia Telescope National FacilityMany prominent stars in our night sky are in fact visual binary systems. α Centauri, 1.338 pc distant is in fact a visual binary with the two stars labelled α Cen A and α Cen B separated by a distance of about 23 Astronomical Units, slightly greater than the distance between Uranus and the Sun.

- Binary Star | Encyclopedia.comBinary stars, often called double stars, refer to pairs of stars sufficiently close to each other in space to be gravitationally bound together. Following the laws of gravitation, each of the components revolves around the common center of mass of the system.
