The Andromeda Galaxy, also known as Messier 31, is a spiral galaxy.

Located approximately 2.5 million light-years away from Earth. It is the closest galaxy to our own Milky Way

The Andromeda Galaxy is approximately 220,000 light-years in diameter, making it slightly larger than the Milky Way.

Andromeda is located in the constellation Andromeda and can be seen with the naked eye in dark, clear skies.

The Andromeda Galaxy is thought to have formed approximately 10 billion years ago.

It has undergone several mergers with smaller galaxies over time, including a recent collision with the dwarf galaxy M32.

Andromeda is currently moving towards the Milky Way at a speed of approximately 75 miles per second. In approximately 4.5 billion years, the two galaxies are expected to collide and merge.

Its proximity and similarity to the Milky Way make it a valuable object for studying galaxy formation and evolution.
