Many stars have optical companions, and the set of criteria for what constitutes an optical double star is not clear-cut. It is suggested that editors determine whether or not stars should be added to this category by consulting the Washington Double Star Catalog or a similar authoritative catalog of double and multiple stars.
The Washington Double Star Catalog, or WDS, is a catalog of double stars, maintained at the United States Naval Observatory. The catalog contains positions, magnitudes, proper motions and spectral types and has entries for (as of January 2024) 157,012 pairs of double stars. The catalog also includes multiple stars.
Epsilon Lyrae, the Double Double. The widest two components of the system are easily separated when viewed through binoculars, or even with the naked eye under excellent conditions.

Double Star is a two-player game about space warfare, [1] and operates on the belief that warfare between two star systems is possible but expensive and difficult. [2]This game is based in a binary star system, where the two stars orbit each other, and each star has a different human colony orbiting it; one is of Chinese descent, the other Arab.
