Barnard's star moving on the sky years 2017-2022. Barnard's star is a red dwarf in constellation of Ophiuchus. It is the second closest star to us after Alpha Centauri triple star. The mass is 14% of the Sun mass and diameter 20% of Sun. The surface temperature is 3100 degrees and its luminosity is times the brightness of the Sun. Barnard’s star is moving in the sky fast, 10 arch seconds each year. It is moving 142 km/s relative to Sun and it will be closest to us year 11800. Then distance will be light years. But even then it is so faint that it cannot be seen with naked eye. The age is 10 billion years, over twice the age of our Sun. Year 1998 there was a bright flare eruption in Barnard’s star.
