Proxima Centauri (Latin proxima: meaning 'next to' or 'nearest to') is a red dwarf star about 4.2 light-years (3.97×1013 km) distant in the constellation of Centaurus. It was discovered in 1915 by Robert Innes, the Director of the Union Observatory in South Africa, and is the nearest known star to the Sun, although it is too faint to be seen with the naked eye. Its distance to the second- and third-nearest stars, which form the bright binary Alpha Centauri, is 0.237 ± 0.011 ly (15,000 ± 700 astronomical units [AU]). Proxima Centauri may be with Alpha Centauri A and B.
