Barnard's Star is also known as Gliese 699 and informally as Proxima Ophiuchi. Named for the astronomer E. E. Barnard, who discovered it in 1916 and was the first to measure its proper motion. Second closest star system to the Sun and the one with the highest proper motion in the sky - due to its rapid approach to the Sun. Will get as close as 3.8 ly away in 12,000 years. A red dwarf once thought to have a planet around it found due to radial velocity method. Since disproven. A potential target for the 1970's Project Daedelus. It has been determined definitively that no Earth-sized planets orbit in its habitable zone. The nearest system without known planets. The star is very ancient 11-12 Billion Years Old, and is the nearest inactive Red Dwarf Star. It may take another 40 Billion Years before it cools to become a Black Dwarf. Astronomers were surprised to discover that it was a flare star in 2003, and dubbed it V2500 Ophiuchi.
