s of galaxies.

Relative to other local superclusters, Hercules is considered particularly large, being approximately 330 Mly in diameter. There is a vast cosmic void in front of the region that is as big as the superclusters themselves.

The region includes the Abell 2147

, A2151, and A2152 galaxy clusters. An extremely long filament of galaxies has been found, that connects this group of clusters to the Abel A2197 and A2199 pair.

The Hercules Superclusters are near the Coma Supercluster
