Pisces–Cetus Supercluster Complex

It includes the Laniakea Supercluster which contains the Virgo Supercluster lobe which in turn contains the Local Group, the galaxy cluster that includes the Milky Way.

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

[3] The Pisces–Cetus Supercluster Complex is estimated to be about 1.0 billion light-years (Gly) long and 150 million light years (Mly) wide.

Sixty clusters comprise the complex, which is estimated to have a total mass of 1018 M☉.

[4] According to the discoverer, the complex is composed of 5 parts: With its mass of 1015 M☉, our Virgo Supercluster accounts only for 0.1 percent of the total mass of the complex.

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 (here shown as the former Virgo, Hydra, and Centaurus Superclusters)
