Coma Berenices
Coma Berenices is a traditional asterism that has since been defined as one of the 88 modern constellations. It is located near Arcturus, and the constellation Leo to which it formerly belonged, and contains the North Galactic Pole. Its name means ""Berenice's Hair"" (in Greek, via Latin), and refers to the legend of Queen Berenice II of Egypt, who sacrificed her long hair.
