Around 7 to 12 billion years
Barnards star has a mass of between 0.15 and 0.17 solar masses.
Barnard's Star is approximately 6 light years away.
Barnards star has a mass of between 0.15 and 0.17 solar masses.
Barnards Star, approximately 6 light years distant.
Barnard's Star is a very low-mass red dwarf star and has a spectral type of M4V.So it has the colour red.
The name is "Barndard's star". Wikipedia lists it at 3,134 ± 102 Kelvin. (Subtract 273 degrees if you want this in Celsius.) The "plus or minus" refers to the uncertainty (estimated error).
It has a radius of between 0.15 and 0.20 that of our Sun. The Sun has a radius of about 696,000 km, so Barnard's Star has a radius of between 104,400 km and 139,200. Average about 121,800 km

Barnard's Star is located in the Milky Way galaxy, which is the galaxy where our solar system is also located. It is a red dwarf star and is one of the closest stars to our solar system, at a distance of about 6 light-years away.

Barnard's Star is a very low-mass red dwarf star.The estimated surface temperature of the red dwarf known as Barnard's Star is "only" about 3134 K, compared to our Sun's surface temperature of about 5778 K. It radiates mostly in the infrared, and is the closest detected red dwarf to Earth, about 6 light years away.
