Many people wouldn't know about the Andromeda galaxy.
The Andromeda galaxy is 2.537 million light-years away from Earth in the constellation Andromeda. Its 'closeness' to our planet makes it the most distant object visible to the naked eye on Earth. It is the nearest giant galaxy and contains approximately the same number of stars as the Milky way!
