Andromeda

Overview
The Andromeda Galaxy (Numerically classified as M 31 or NGC 224) is a barred spiral galaxy, located near the center of the Local Group approximately 2.5 million light years from the Milky Way galaxy. Andromeda is the largest galaxy in the Local Group, housing over two times as many stars as the Milky Way. Most notably, Andromeda is mostly controlled by Alliance of Andromeda. The massive nature of Andromeda has also made it a great place for resource extraction and colonialism, and as such many colonies have appeared inside Andromeda.
