[3] The cluster spans about ten million light years and has an unusual high proportion of dark matter. [4] The cluster is part of the Hydra-Centaurus Supercluster located 158 million light years from earth. The cluster's largest galaxies are elliptical galaxies NGC 3309 and NGC 3311 and the spiral galaxy NGC 3312 all having a diameter of about 150,000 light years.[5] In spite of a nearly circular appearance on the sky, there is evidence in the galaxy velocities for a clumpy, three-dimensional distribution.[MartinOct 18, 2010
