At a distance of approximately 62.0+5.9−5.5 Mly (19.0+1.8−1.7 Mpc),[2] the Fornax Cluster is the second richest cluster of galaxies within 100 million light-years, although it is much smaller than the Virgo Cluster. It lies primarily in the constellation Fornax, and may be associated with the nearby Eridanus Group. Although small as clusters of galaxies go, the Fornax Cluster is a valuable source of information about the evolution of such clusters, showing the effects of a merger of a subgroup with the main group,[3] which in turn lends clues about the associated galactic superstructure.[4] At the centre of the cluster lies NGC 1399.[2] Other cluster members include: NGC 1427A and NGC 1404.[2]
