The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of only ten galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide. Andromeda is accompanied b y at least 10 satellite galaxies..
It is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years; 2.4×1019 km) from Earth.
It gets its name from the area of the sky in which it appears, theconstellation of Andromeda, which was named after the mythological princess Andromeda.
Andromeda, daughter of Cassiopeia, in the Greek myth, was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth.
The Persian astronomer Abd al-Rahman al-Sufi wrote a line about the chained constellation in his Book of Fixed Stars around 964, describing it as a "small cloud".
Star charts of that period have it labeled as the Little Cloud. The first description of the object based on telescopic observation was given by German astronomer Simon Marius on December 15, 1612. Charles Messier catalogued it as object M31 in 1764 and incorrectly credited Marius as the discoverer, unaware of Al Sufi's earlier work.
