![M31 The Andromeda Galaxy, taken by Dave Frost. The Andromeda Galaxy (/ænˈdrɒmɪdə/), also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way.[4] Its name stems from the area of the Earth's sky in which it appears, the constellation of Andromeda. The 2006 observations by the Spitzer Space Telescope revealed that the Andromeda Galaxy contains approximately one trillion stars,[10] more than twice the number of the Milky Way's estimated 200 to 400 billion stars.[13] The Andromeda Galaxy's mass is estimated to be around 1.76 times that of the Milky Way Galaxy (~0.8-1.5×1012 solar masses [9][10] vs the Milky Way's 8.5×1011 solar masses), though a 2018 study found that the Andromeda Galaxy's mass is roughly the same as the Milky Way's.[9] The Andromeda Galaxy, spanning approximately 220,000 light-years, is the largest galaxy in the Local Group, which is also home to the Triangulum Galaxy and other minor galaxies.](http://www.chesterfield-as.org.uk//wp-content/gallery/galaxies/08-Aug-Andromeda.jpg "M31 The Andromeda Galaxy, taken by Dave Frost.
