The Eridanus Supercluster is a massive group of galaxies located in the constellation of Eridanus. It is part of a larger structure known as the Laniakea Supercluster, which includes our own Milky Way Galaxy. The Eridanus Supercluster contains several galaxy clusters and is one of the largest known superclusters in the universe. This supercluster is characterized by its gravitational pull, which influences the motion of nearby galaxies. It plays a significant role in the large-scale structure of the universe, helping astronomers understand how galaxies are distributed and how they interact with one another over vast distances.
