'''Proxima Centauri''' is a spectral class M5.5 Red Dwarf [[star]] in the constellation of Centaurus.  At just over 4.22 [[Light year]]s away Proxima Centauri is the nearest star to the [[Solar System]].  It was first discovered in 1915 by the astronomer Robert Innes and is not visible by the naked eye. It is often considered the third star in the [[Alpha Centauri]] system due to having the same proper motion as Alpha Centauri A & B.  Due to the star's great distance of around 15,000AUs (roughly one-fifth of a light year) from Alpha Centauri A & B, astronomers debate if Proxima Centauri is gravitationally bound to the other two stars.
