Coma Berenices is an ancient asterism that has since been defined as one of the 88 modern constellations. It is located in the fourth galactic quadrant, between Leo and Bootes, and is visible in both celestial hemispheres. Introduced to the Western astronomy in the 3rd century BC by Conon of Samos, its name means "Berenice's Hair" (in Greek, via Latin), referring to Queen Berenice II of Egypt, who sacrificed her long hair as a votive offering.
