Andromeda is a spiral galaxy located about 2.5 million light-years away from Earth in the direction of the Andromeda constellation. It is the closest to the Milky Way and can be observed with the naked eye depending on the atmospheric conditions. It is estimated to contain about 500 billion stars and is on a collision course with our galaxy. Computer simulations show that star collisions will be rare, revealing how far apart they are from each other.
