Earth is located in the Orion Arm, a minor spur of the Milky Way, about 27,000 light-years from the galaxy's center. Our solar system is about halfway between the galaxy's center and its outer edge.
The Milky Way is a member of the Local Group, which is a small group of galaxies that includes the Andromeda Galaxy, the Triangulum Galaxy, and several smaller galaxies. The Local Group is located within the Virgo Supercluster, which is a large cluster of galaxies that contains several thousand galaxies.
The Virgo Supercluster is part of the Laniakea Supercluster, which is a vast supercluster of galaxies that is estimated to contain over 100,000 galaxies. Laniakea is the largest known structure in the universe and is thought to be about 520 million light-years across.
