A group of more than 30 galaxies that includes 2 large spiral galaxies—the Milky Way and Andromeda—as well as numerous smaller galaxies, many of which are dwarfs. The Local Group has a diameter of approximately 10 million light-years, with its gravitational center located between our galaxy and the Andromeda galaxy. It is part of a larger grouping known as the Virgo supercluster.
