Also known as M31 and NGC 224, this giant spiral galaxy is the closest major galaxy to the Milky Way. Both belong to the Local Group. Several relativistic craft, including linelayers with wormholes, have left towards the galaxy through history, although the chances that they will reach it intact are probably remote.

- Galaxy, Irregular - Text by M. Alan Kazlev
A galaxy of amorphous or chaotic appearance, possessing large clouds of gas and dust, and both Population I and Population II stars, but no spiral arms or nucleus. They are thought to result from a collision with a larger galaxy, pulling them out of shape. Most have relatively low mass (about a hundred million to ten billion stars). About 25% of all galaxies are irregular.
- Galaxy, Spiral - Text by M. Alan Kazlev
A disk-shaped galaxy with a spiral pattern of arms, typically containing 1010 or more solar masses of stars, dust, and gas.
