The Hydra-Centaurus Supercluster (SCl 128), or the Hydra and Centaurus superclusters, is a supercluster in two parts and the closest neighbour of Milky Way's Virgo Supercluster.
The cluster includes four large galaxy clusters in the Centaurus part
and the proximate
- Hydra Cluster (A1060) and
- Norma cluster (A3627).
Apart from the central clusters, which are 150 to 200 millions of 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 (ACO 3627). 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[1]
