The Hercules Superclusters (SCl 160) refers to a set of two nearby superclusters of galaxies.[2]
Relative to other local superclusters, Hercules is considered particularly large, being approximately 330 Mly in diameter. The Northern Local Supervoid lies in front of the superclusters, and is as big as the superclusters themselves.[3] The redshifts of the member galaxies lie between 0.0304 and 0.0414.[1]
The region includes Abell 2147, Abell 2151 (Hercules Cluster), and Abell 2152 galaxy clusters.[4][5] An extremely long filament of galaxies has been found, that connects this group of clusters to the Abell 2197 and Abell A2199 pair.[5] Abell 2162 in the nearby constellation Corona Borealis is also a member.[6]
The Hercules Superclusters are near the Coma Supercluster, helping make up part of the CfA2 Great Wall.[7]
