后发座超星系团是邻近银河的超星系团，拥有后发座星系团（阿贝尔1656）和狮子座星系团 （阿贝尔1367）两个星系团。后发座超星系团距离地球大约3亿光年，位于长城的中心，是最接近我们所在的室女座超星系团中的超星系团。他的外型大致是球形，直径大约二千万光年，包含3,000个以上的星系。它位于后发座，是第一个被发现的超星系团，后发座超星系团帮助天文学家了解宇宙的结构。

The Coma Supercluster (SCl 117) is a nearby supercluster of galaxies comprising the Coma Cluster (Abell 1656) and the Leo Cluster (Abell 1367). Located 300 million light-years from Earth, it is in the center of the Great Wall. The Coma Supercluster is the nearest massive cluster of galaxies to our own Virgo Supercluster. It is roughly spherical, about 20 million light-years in diameter and contains more than 3,000 galaxies. It is located in the constellation Coma Berenices. Being one of the first superclusters to be discovered, the Coma Supercluster helped astronomers understand the large scale structure of the universe.
