Barnard's Star is a star (in fact, a red dwarf) in the constellation Ophiuchus which is notable for having the largest [proper motion]? of any star (other than the Sun) as seen from Earth. This large proper motion was discovered by the astronomer E. E. Barnard in 1916. Lying at a distance of about 6 light years, it is the fifth closest known star to Earth, being beaten only by the Sun and the three components of the Alpha Centauri system. |

Barnard's Star is a star in the constellation Ophiuchus which is notable for having the largest [proper motion]? of any star (other than the Sun) as seen from Earth. This large proper motion was discovered by the astronomer E. E. Barnard in 1916. Lying at a distance of about 6 light years, Barnard's Star is the fifth closest known star to Earth (see Star/Nearest). Only the Sun and the three components of the Alpha Centauri system are closer. But Barnard's Star is a red dwarf (spectral type M4), so despite its proximity it is too faint to see without a telescope or powerful binoculars. Its apparent magnitude is 9.54. Barnard's Star is also known as HIP 87937, and various other unfriendly names.
