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 2199 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]
In the 1930s, Harlow Shapley studied the structure of the distribution of galaxies in the constellation of Hercules, and was probably first to discover the existence of a supercluster in that region. However, this was not confirmed until the 1970s. In 1976, Massimo Tarenghi suggested that the A2151 cluster was part of a single supercluster, and at a conference in Estonia in 1977, he, together with several other astronomers, presented evidence that it was indeed a supercluster that appeared in that region.[2]

Der Herkules-Superhaufen ist ein Superhaufen und Teil der Großen Mauer.[1] Eigentlich besteht der Superhaufen aus zwei Superhaufen, einer südlicheren Region mit dem Namen BS 15 und einer nördlicheren Region mit dem Namen BS 16.[2] Der Superhaufen hat eine Ausdehnung von 100 Mpc[3] und eine Masse von 7,6×1015 Sonnenmassen.[4]

[ru] Сверхскопление Геркулеса
Сверхскопление Геркулеса (SCl 160, англ. Hercules Superclusters) — сверхскопление галактик в созвездии Геркулеса. Состоит из двух соседних, связанных между собой, сверхскоплений галактик, которые часто упоминаются как северная и южная части единого сверхскопления Геркулеса. Северная часть располагается на расстоянии 400 миллионов световых лет, чуть дальше, на расстоянии 500 миллионов световых лет, лежит южная часть сверхскопления[2].
