Koposov 1 is a low-luminosity globular cluster in the constellation Virgo in the halo of the Milky Way galaxy. It was discovered, along with globular cluster Koposov 2 by S. Koposov et al. in 2007. Koposov 1 and Koposov 2 were described by their discoverers as the "lowest luminosity globular clusters orbiting the Milky Way," along with AM 4, Palomar 1, and Whiting 1.[2]
