DescriptionThis constellation commemorates one of the few historical people immortalized in the stars. Queen Berenice II of Egypt vowed to sacrifice her beautiful golden hair to Aphrodite in exchange for her husband Ptolemy III's safe return from war against Syria. When he returned victorious, she cut off her hair and placed it in the temple — but the offering vanished. The court astronomer Conon of Samos announced that the grateful gods had placed it among the stars. The constellation hosts the Coma Cluster — one of the nearest and richest galaxy clusters, containing over 1,000 galaxies about 320 million light-years away. It also contains the North Galactic Pole.
