Short description: Series of galaxy clusters in the constellation Virgo

The Virgo III Groups, or Virgo III Cloud, are a series of at least 75 galactic clusters and individual galaxies stretching approximately 40 megalight-years (12,264,055.75 parsecs) off the eastern edge of the Virgo Supercluster.^[1]^[2]^[3] Parts of it are in the constellations Virgo, Libra, and Serpens Caput. It is located approximately 65 Mly (19,929,090.60 pc) to 85 Mly (26,061,118.47 pc) from the Solar System, at a right ascension of 13^h 30^m to 15^h 20^m.^[1]

These clusters include:^[1]
