It was discovered, along with globular cluster Koposov II by S. Koposov et al. in 2007. Koposov I and Koposov II 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] References1. ^1 2 3 {{cite web|title=Koposov 1|url=http://spider.seds.org/spider/MWGC/koposov1.html|publisher=Spider|accessdate=15 February 2013}} {{Milky Way}}{{Sky|11|59|18.05|+|12|15|36.0}}{{DEFAULTSORT:Koposov I}}2. ^1 {{cite journal | last1 = Koposov | first1 = S. | last2 = de Jong | first2 = J.T.A. | last3 = Belokurov | first3 = V. | last4 = Rix | first4 = H.-W. | last5 = Zucker | first5 = D.B. | last6 = Evans | first6 = N.W. | last7 = Gilmore | first7 = G. | authorlink7 = Gerard F.
