The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies[4] some 500 million light-years distant in the constellation Hercules.

It is rich in spiral galaxies and shows many interacting galaxies.

[5] The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.

[6] The cluster's brightest member is the giant elliptical galaxy NGC 6041.
