Leo II Groups

The Leo II Groups, or Leo II Cloud, are a series of at least 110 galactic clusters and individual galaxies stretching approximately 30 Mly (9.2 Mpc) ecliptic west of the edge of the Virgo cluster.^[1][2] It is located approximately 65 Mly (20 Mpc) to 95 Mly (29 Mpc) from the Solar System, at a right ascension of 10^h 00^m to 11^h 40^m .^[1]
