1911 Encyclopædia Britannica/Coma Berenices
COMA BERENICES ("BERENICE'S HAIR"), in astronomy, a constellation of the northern hemisphere; it was first mentioned by Callimachus, and Eratosthenes (3rd century B.C.), but is not included in the 48 asterisms of Ptolemy. It is said to have been named by Conon, in order to console Berenice, queen of Ptolemy Euergetes, for the loss of a lock of her hair, which had been stolen from a temple to Venus. This constellation is sometimes, but wrongly, attributed to Tycho Brahe. The most interesting member of this group is 24 Comae, a fine, wide double star, consisting of an orange star of magnitude 5½, and a blue star, magnitude 7.
