M45 (Pat Devine) M45 also known as the Pleiades or the Seven Sisters from last night. M45 is an open star cluster and lies about 400 light years away located in the constellation of Taurus. The cluster contains 500 stars over a sphere that is 14 light years wide. The cluster is moving at a different radial velocity from the nebulosity suggesting the stars are crossing the path of dust in a molecular cloud. The stars in the Pleiades cluster formed in the last 100 million years and contains a number of hot, blue, extremely luminous B-type stars and is one of the nearest star clusters to Earth.
