Galactic Groups

Galaxies appear to assimilate in groups throughout the Universe. For example, the Milky Way and Andromeda galaxies are members of The Local Group , more than 54 gravitationally bound galaxies, most are dwarf galaxies. Smaller galactic groups are a part of galaxy superclusters. The Local Group is part of the Virgo Supercluster, composed of at least 100 galaxy groups and clusters.
