The barred spiral galaxy NGC 1300 is a well-known member of the Eridanus Cluster.

The Eridanus Cluster is a galaxy cluster roughly Шаблон:Convert from Earth, containing about 73 main galaxies and about 200 total galaxies. About 30% have Hubble classifications of elliptical or S0 and the remaining 70% are spiral or irregular.[1] These galaxies reside in smaller groups which are all loosely gravitationally bound to each other, suggesting that the system is still condensing from the Hubble flow and may eventually form a cluster of about 1014 Шаблон:Solar mass. A low velocity dispersion compared to that of, for example, the Coma cluster, supports this hypothesis.[2] The Eridanus Cluster is located in the constellation Eridanus near the Fornax Cluster, and is sometimes called the "Fornax II Cluster".[3]
