It is considered a member of the M51 Group although it is actually relatively isolated from other galaxies.[2] It is approximately 15 kiloparsecs (49,000 light-years) across and contains more than 200 stars with an apparent magnitude of greater than 23.5.[1] References1. ^1 2 {{cite journal| title= Distances to Eight Nearby Isolated Low-Luminosity Galaxies|journal = Astronomy Letters|volume = 25|issue = 5|pages = 322| date = 1999| author=M.
