LocationLocated 300 million light-years from Earth,[1] it is in the center of the Great Wall and a part of Coma Filament.[2] The Coma Supercluster is the nearest massive cluster of galaxies to our own Virgo Supercluster.[3] SizeIt is roughly spherical, about 20 million light-years in diameter and contains more than 3,000 galaxies. It is located in the constellation Coma Berenices. Being one of the first superclusters to be discovered, the Coma Supercluster helped astronomers understand the large scale structure of the universe. See also
