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]
