The complex comprises about 60 clusters and is estimated to have a total mass of 1018M☉.[4] According to the discoverer, the complex is composed of 5 parts:
With its mass of 1015M☉, our Virgo Supercluster accounts only for 0.1 percent of the total mass of the complex.
The complex was named after the Pisces–Cetus Superclusters, which are its richest superclusters.

The Pisces–Cetus Supercluster Complex is the very long chain of galaxies from the Pisces–Cetus Superclusters, Sculptor Superclusters, the Perseus–Pisces Supercluster and the Laniakea Supercluster. (Shown at the center)
