Milky Way Galaxy
The Milky Way Galaxy as seen from Earth.
The Andromeda Galaxy is located approximately 2,480,000 light-years away from the Milky Way Galaxy.1
While some earlier estimates placed it at about 2,000,000 light-years away, current astronomical data identifies the distance as 2.48 million light-years. Both galaxies are the dominant members of the Local Group, a collection of galaxies held together by their mutual gravitational attraction.23
