Galaxy cloud
"galaxy cluster cloud" redirects here. For the mid-20th-century usage for a 'cloud of clusters', see galaxy supercluster. For the early-through-mid-20th-century usage, see galaxy groups and clusters.
A galaxy cloud or cloud of galaxies is a group of galaxy clusters and a substructure of a supercluster. Clouds are regions of higher density of clusters and galaxies within superclusters. 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.
