The Perseus–Pegasus Filament is a galaxy filament containing the Perseus–Pisces Supercluster and stretching for roughly a billion light-years (or over 300/h Mpc). Currently, it is considered to be one of the largest known structures in the universe. This filament is adjacent to the Pisces–Cetus Supercluster Complex.

👉 Perseus–Pegasus Filament in the context of Pisces–Cetus Supercluster Complex
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; 6.17×10 kilometres) away from Earth. A supercluster complex is defined as container of several dozens of rich clusters and large superclusters.
This filament is adjacent to the Perseus–Pegasus Filament.

Perseus–Pegasus Filament in the context of Perseus–Pisces Supercluster
The Perseus–Pisces Supercluster (SCl 40) is one of the largest known structures in the universe. Even at a distance of 250 million light-years, this chain of galaxy clusters extends more than 40° across the northern winter sky. The Perseus–Pisces Supercluster is one of two dominant concentrations of galaxies (the other being the Laniakea Supercluster) in the nearby universe (within 300 million light-years). This supercluster also borders a prominent void, the Taurus Void, and is part of the Perseus–Pegasus Filament, which stretches for roughly a billion light years.
