M45) is one of the brightest open clusters recently and one of the most famous clusters. It is located in Taurus and can be seen with the naked eye under a clear night sky. Six bright stars are usually visible to the naked eye. The apparent diameter of the Pleiades cluster is about 2, forming a bucket shape. Is a very young star cluster, its age is about 50 million years. The Pleiades is also a moving star cluster. The Pleiades cluster contains more than 3,000 stars, with a width of about 13 light years, a distance from the solar system 128 parsec (4 17 light years) and a true diameter of about 4 parsec.
