Target Details
Barnard's Star is a very low mass red dwarf which is located around 6 light-years from Earth. It is the fourth nearest individual star to the Sun, and the second nearest if you count the Alpha Centauri system as 1 entity. It is the red star slightly above the centre of the image.

Interestingly, because it is so close to Earth it is perceived to move by 10.3 arcseconds per year. This is the largest proper motion of any star relative to the Sun.

It has a magnitude of 9.5, making it too dim to see with the naked eye, and is between 7 and 12 billion years old. This is considerably older than the Sun, which is a mere 4.5 billion years old.
