The Virgo II Groups, also known as the Virgo II Cloud, Virgo Southern Extension, or the Virgo S Cloud, are a series of at least 100 galactic clusters and individual galaxies stretching approximately 30 megalight-years (9,198,041.81 parsecs ) off the southern edge of the Virgo Supercluster. [1] [2] [3] It is located approximately 55  Mly (16.86  Mpc ) to 80  Mly (24.53  Mpc ) from the Solar System, at a right ascension of 12h 00m to 13h 30m. [1]
