The Hercules Cluster (Abell 2151) is a cluster of about 100 galaxies some 650 million light-years distant (z = 0.036[3]) in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies.[4] The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.[1]
