The Laniakea Supercluster (considered the Local Supercluster) is a Supercluster with 300-500 Galaxy Clusters, with 100,000 galaxies including the Milky Way, stretched out over 160 megaparsecs, with a mass of about 1017 solar masses. It was identified and labeled in September 2014. It is the combination of four groups traditionally labeled superclusters:
