The Horologium Supercluster, also known as Horologium-Reticulum Supercluster, consisting of SCl 48 and SCl 49) is a massive supercluster; spanning about 550 million light-years, it has a mass of 1017solar masses, similar to that of the Laniakea Supercluster that 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°.
The nearest part of the supercluster is 700 million light-years (z=0.063) away from Earth, while the far end of it is 1.2 billion light-years, visible in the constellations Horologium and Eridanus. The Horologium Supercluster has about 5,000 galaxy groups (30,000 giant galaxies and 300,000 dwarf galaxies). It includes the cluster Abell 3266.
