Coma Berenices (abbr. Com, gen. Comae Berenices)





A very faint northern constellation considered to be part of Leo by the Greeks but made separate by Gerardus Mercator in 1551. It lies between Canes Venatici to the north, Virgo to the south, Leo to the west, and Bootes to the east, and contains the north galactic pole. Although devoid of bright stars, Coma Berenices abounds in galaxies and other deep sky objects, details of some of which are given below.
