Centauri
1561VI005 is part of Alpha Centauri, the closest star system to Earth. It consists of three stars, Alpha Centauri A, B, and Proxima Centauri, within 4.3 light years of Earth. 1561VI005 is one of the two images sent back to Earth by the Hubble Space Telescope from the system in 2001. The two images showed the two stars, Alpha Centauri A and B, for the first time separated from each other. 1561VI005 showed the two stars in the same area of the sky, but with Alpha Centauri A being slightly brighter and larger. This image revealed that the stars are about 2.4 arcseconds apart and are of nearly equal brightness. This image was integral in helping to confirm that the two stars were part of a binary system, orbiting each other from an average distance of 23 astronomical units.
