Hydra-Centaurus Supercluster


The Hydra-Centaurus Supercluster, or the Hydra and Centaurus Superclusters, is a supercluster in two parts, the closest neighbour of Virgo Supercluster.

Hydra-Centaurus

The cluster includes four large galaxy clusters in the Centaurus part
and the proximate
Apart from the central clusters, which are 150 to 200 million light years away, several smaller clusters belong to the group.
Within the proximity of this supercluster lies the Great Attractor, dominated by the Norma Cluster. This massive cluster of galaxies exerts a large gravitational force, causing all matter within 50 Mpc to experience a bulk flow of 600 km/s toward the Norma Cluster

Laniakea

A 2014 announcement says that the Centaurus Supercluster is just a lobe in a greater supercluster, Laniakea, that is centered on the Great Attractor. That supercluster would include the Virgo Supercluster, therefore including the Milky Way where Earth resides.
