Horologium-Reticulum Supercluster

The Horologium-Reticulum Supercluster, is a massive supercluster spanning around 550 million light-years.[1] It has a mass of around 1017 solar masses, similar to that of the Laniakea Supercluster, which houses the Milky Way. It is centered on coordinates right ascension 03h 19m and declination −50° 02′, and spans an angular area of 12° × 12°.[2]
