Southern Supercluster

The Southern Supercluster is a nearby supercluster located around 19.5 Mpc (63.6 Mly) in the constellations of Cetus, Fornax, Eridanus, Horologium, and Dorado. It was first identified in 1953 by Gérard de Vaucouleurs.

The Southern Supercluster contains three main clusters, the Dorado, Fornax, and Eridanus clusters, along with many other groups of galaxies.

In 2014, it was announced that the Southern Supercluster Strand is a lobe in a greater supercluster, Laniakea, that is centered on the Great Attractor. This would mean that the Southern Supercluster Strand's components, the Southern Supercluster and the Telescopium−Grus Cloud would be part of this new supercluster. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster.
