Constellation: Ophiuchus

temp.: 3,236 F

radius: 136,300km

age: about 10,000,000,000

low mass red dwarf about 6 light-years away from earth. The star is named after the american astronomer E.E. Barnard. Although he wasn’t the first to observe it (It first appeared on Harvard’s plates in 1888 and 1890) it is not visible with the naked eye. It is not as bright in visible light than it is in infrared. It is in the main sequence. Barnard’s star was an emerald nebula.
