New shot of Proxima Centauri, our nearest neighbour
Shining brightly in this Hubble image is our closest stellar neighbour: Proxima Centauri.
Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible to the naked eye. Its average luminosity is very low, and it is quite small compared to other stars, at only about an eighth of the mass of the Sun.
