Description

Our neighboring Andromeda galaxy, or M31 in the Messier catalogue, is a spiral galaxy with a diameter of about 220,000 light years and is located about 2.5 million light years from Earth. This galaxy is approaching us at a speed of 420,000 km/h and will conclude in a cosmic collision of galaxies in about 5.86 billion years, forming a single galaxy, which we would name Lactomeda, being the merger of the Milky Way and Andromeda.
