Located in the constellation of Coma Berenices is a small, dim galaxy known as M91. Until recently, this galaxy had been missing. Messier's notes had given the wrong position for this object. An amateur astronomer from Texas finally figured out its true location in 1969. This galaxy is classified as a barred spiral. The center part of the galaxy displays a prominent bar-shape, which can be seen even in small telescopes. M91 is a member of the Virgo cluster of galaxies and it located about 60 million light-years from Earth. It is receding from us at a rate of 400 km/sec. With a magnitude of only 10.2 it is best observed with a large telescope.
