A galaxy cloud or cloud of galaxies is a group of galaxy clusters and a substructure of a supercluster. They have a typical characteristic dimension of 50 Mpc/h. About 25% of all galaxies are members in clouds.[1]
The Virgo Supercluster (to which the Milky Way belongs) contains the Virgo cluster, the Canes Venatici Cloud and the Virgo II Cloud.
