The Milky Way is part of the Local Group, a small cluster of galaxies that also includes the Andromeda Galaxy, the Triangulum Galaxy, and about 54 other smaller galaxies. Additionally, the Milky Way is part of the Virgo Supercluster, a much larger structure of galaxies. Over time, galaxies within these groups interact gravitationally, leading to mergers and other phenomena.
