But Proxima wont be the nearest for much longer.
Lying at a distance of about 5.96 light-years, Barnard's Star is the nearest star in the constellation Ophiuchus and is also the second closest known star system to the Sun and the fourth closest known individual star after the three components of the Alpha Centauri system
Barnard's Star is approaching the Sun so rapidly that it will be the nearest star around AD 11,800, at a distance of 3.8 light-years. That is some going, getting two light years closer in the space of 9800 years,
Barnard's Star was discovered by the astronomer E. E. Barnard in 1916. Barnard measured its proper motion to 10.3 arcseconds per year, which remains the largest known proper motion of any star relative to the Sun, Its true velocity relative to the Sun is calculated as between 139.7 and 142.7 km/s
Like Proxima it is a red dwarf,
