The Pleiades, also known as Seven Sisters and Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus. At a distance of about 444 light-years, it is among the star clusters nearest to Earth and is the Messier object nearest to Earth, being the star cluster most obvious to the naked eye in the night sky.
