Lalande 21185 is a magnitude- 7.5 red-dwarf star in the constellation Ursa Major. It lies about midway between the constellation Leo and the Big Dipper asterism. At a distance of 8.3 ly, it is the fourth nearest star system, because the Alpha Centauri system consists of three stars. The closest member of the Alpha Centauri trio is Proxima Centauri, a magnitude-11 red dwarf. Next comes Barnard's Star, a magnitude-9.5 red dwarf, then Wolf 359, a magnitude-13.5 red dwarf, and then Lalande 21185. From this list of the six nearest stars, four of them are too faint to be seen with the unaided eye.
