Barnard's Star

noun

Bar·nard's Star ˈbär-nərdz-

astronomy

: a red dwarf star of the ninth magnitude that is located approximately six light years away in the constellation of Ophiuchus

Such is the case with Barnard's Star. It is the fourth closest star to Earth at only 36 trillion miles away, yet you'll need a telescope to see it.—

Tom Burns, Columbus (Ohio) Dispatch, 16 July 1995

Note: Barnard's Star is notable because it is one of the closest stars to the Sun. Only the Alpha Centauri system is closer.
