The Hydra-Centaurus Supercluster, or the Hydra and Centaurus superclusters, is a
superclusterin two parts and the closest neighbourof Milky Way's Virgo Supercluster.
The cluster includes four large galaxy clusters in the Centaurus part
*A3526 (Centaurus cluster),
A3581and 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.
