The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years away in the constellation Andromeda. It is also known as Messier 31, M31, or NGC 224, Andromeda is the nearest spiral galaxy to us. It is one of the farthest objects visible to the naked eye, and can be seen even from urban areas with binoculars. Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way Galaxy, the Triangulum Galaxy, and about 30 other smaller galaxies. Although the largest, Andromeda may not be the most massive, as recent studies suggest that the Milky Way contains more dark matter and may be the most massive in the group.
