The second most massive galaxy cluster next to El Gordo is RCS2 J2327, a galaxy cluster with the mass of 2 quadrillion suns. Also has a systematic designation of ACT-CL J0102-4915. [6] [7] [8] Musket Ball Cluster: Named in comparison to the Bullet Cluster, as this one is older and slower galaxy cluster merger than the Bullet Cluster.
These four near-equals at the core of galaxy cluster CL 0958+4702 are in the process of merging. [149] Galaxy protocluster LBG-2377: z=3.03 This was announced as the most distant galaxy merger ever discovered. It is expected that this proto-cluster of galaxies will merge to form a brightest cluster galaxy, and become the core of a larger galaxy ...
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.

Shapley 20 Cluster: 03 h 30 m 34.6 s: −52° 33′ 12″ 3 I-II 3158: Shapley 17 Cluster: 03 h 42 m 39.6 s: −53° 37′ 50″ 2 I-II 3192: MCS/MACS J0358.8-2955 Eridanus: Comprises such a huge amount of mass that the galaxy cluster noticeably curves spacetime around it, making it into a gravitational lens.

Abell divided the clusters into six "richness groups", depending on the number of galaxies in a given cluster that lie within the magnitude range m 3 to m 3 +2 (the average number of galaxies per cluster for the entire catalog was 64): Group 0: 30–49 galaxies; Group 1: 50–79 galaxies; Group 2: 80–129 galaxies; Group 3: 130–199 galaxies
