Encyclopedic overview
Luyten's Star /ˈlaɪtənz/ (GJ 273) is a red dwarf in the constellation Canis Minor located at a distance of 12.35 light-years (3.79 parsecs) from the Sun. It has a visual magnitude of 9.9, making it too faint to be viewed with the unaided eye. It is named after Willem Jacob Luyten, who, in collaboration with Edwin G. Ebbighausen, first determined its high proper motion in 1935. The star has two confirmed planets and two candidate planets, of which Luyten b is in the circumstellar habitable zone.
