[PAR] [TLE] Virgo Supercluster [SEP] The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies that contains the Virgo Cluster in addition to the Local Group, which in turn contains the Milky Way and Andromeda galaxies.  At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years).  It is one of about 10 million superclusters in the observable universe. [PAR] [TLE] Local Sheet [SEP] The Local Sheet in astronomy is a nearby region of the observable universe where the Milky Way, the members of the Local Group and other galaxies share a similar peculiar velocity.  This region lies within a radius of about 7 Mpc , 1.5 Mly thick, and galaxies beyond that distance show markedly different velocities.  The Local Group has only a relatively small peculiar velocity of with respect to the Local Sheet.  Typical velocity dispersion of galaxies within the Local Sheet is only in the radial direction.  All nearby bright galaxies belong to the Local Sheet.  The Local Sheet is part of the Local Volume and is in the Virgo Supercluster (Local Supercluster).
