Pisces–Cetus Supercluster Complex

The Pisces–Cetus Supercluster Complex is a complex of galaxy superclusters or galaxy filament that includes the Virgo Supercluster (the supercluster in which the Local Group, the galactic cluster that includes the Milky Way Galaxy, is located).[1]


Astronomer R. Brent Tully of the University of Hawaii’s Institute of Astronomy identified the Complex in 1987.[2]


The Pisces–Cetus Supercluster Complex is estimated to be about 1.0 billion light years long and 150 million light years wide. It is one of the largest structures identified so far in the universe, but is exceeded by the 1.37 billion-light-year long Sloan Great Wall, 4 billion light-year long Huge-LQG, and the 10 billion light-year long Hercules-Corona Borealis Great Wall.

The complex comprises about 60 clusters and is estimated to have a total mass of 1018 M.[3] According to the discoverer, the complex is composed of 5 parts:

  1. The Pisces–Cetus Supercluster
  2. The Perseus–Pegasus chain, including the Perseus-Pisces Supercluster
  3. The Pegasus-Pisces chain
  4. The Sculptor region, including the Sculptor Supercluster and Hercules Supercluster
  5. The Virgo–Hydra-Centaurus Supercluster, which contains our Virgo Supercluster (Local Supercluster) as well as the Hydra-Centaurus Supercluster.[3]

With its mass of 1015 M, our Virgo Supercluster accounts only for 0.1 percent of the total mass of the complex.
