Andromeda galaxy, located in Andromeda, is a spiral galaxy with a huge disk structure, with a diameter of 220,000 light years and a distance of 2.54 million light years from the Earth. It is the closest galaxy to the Milky Way. The messier number of Andromeda galaxy is M3 1 and the NGC number is NGC 224. In autumn, we first find the famous autumn quadrangle of Pegasus, and then extend the diagonal of the star from the southwest corner to the northeast corner by about 1 time. We can find an inconspicuous star in this place slightly to the north, but if we look at it through a telescope, it will become unusual. It is not just a light spot like other stars, but an oval light spot that looks like a spindle. This is the Andromeda galaxy and the farthest celestial body visible to the naked eye.
