The Milky Way's main companion galaxy is the Andromeda Galaxy, also known as M31. It is the closest spiral galaxy to the Milky Way and is on a collision course with it, expected to merge in about 4.5 billion years. Additionally, the Milky Way has several smaller companions, including the Large and Small Magellanic Clouds.
