The Pisces–Cetus Supercluster Complex (Pisces–Cetus SCC) or the local superstructure is a galaxy supercluster complex (SCC) that includes the Virgo Supercluster as its outlying member (later confirmed to be part of the Laniakea), which in turn contains the Local Group, the galaxy group that includes the Milky Way. The complex was named after the Pisces–Cetus Superclusters, which are its richest and most prominent superclusters and reside in as its core and of its main plane, located at roughly 200 megaparsecs (652 million light-years; 6.17×1021 kilometres) away from Earth. A supercluster complex is defined as container of several dozens of rich clusters and large superclusters.
