The brightest member galaxy is the elliptical galaxy NGC 4696 (~11m). The Centaurus cluster shares its supercluster, the Hydra–Centaurus Supercluster, with IC 4329 Cluster and Hydra Cluster.

The cluster consists of two different sub-groups of galaxies with different velocities.<ref name=":0">{{cite journal | bibcode = 1986MNRAS.221..453L | title=The Centaurus cluster of galaxies.
