The Caelum Supercluster, also known as SCl 59, may be a massive supercluster; spanning 910 million light-years, it is perhaps the largest galaxy supercluster in the universe.^{[citation needed]} It has a mass of 2×10¹⁷ solar masses, 1.7 times the mass of Laniakea Supercluster and of Horologium Supercluster. It is centered on coordinates right ascension 04^h 43^m and declination −33° 30′.^[2]

The nearest part of the supercluster is 1.4 billion light-years away from Earth, while the far end of it is 2.31 billion light-years, visible in the constellations Caelum. The Caelum Supercluster has about 8,300 galaxy groups (50,000 giant galaxies and 500,000 dwarf galaxies).
