The Pin Wheel Nebula and the Black Eye Galaxy are in Coma Berenices. It is a mid-sized constellation with an amber color. Our word for varnish comes from a linguistic derivative of Berenices. Coma Berenices was introduced to Western astronomy by Conon of Samos. Samos was the court astronomer of Egypt in the 3rd Century. The constellation is named to honor Berenice II, consort of Ptolemy III Euergetes.  Constellations nearby include Boötes, Ursa Major, Leo, Virgo, and Canes Venatici. It contains a galactic supercluster, one star cluster, two galactic clusters, and eight Messier objects.

Mythology of the Constellation Coma Berenices 


This is the only modern constellation named for a historic figure. Bernice was an Egyptian princess in the third century B.C. She promised to shave her head in sacrifice to Venus. In return, her brother Ptolemy IX, the Pharoah, returned safely from battle in Syria and Babylon.  After his safe return her hair disappeared overnight before the hair cutting ceremony. The missing hair was discovered by court astronomers that evening between Boötes and Leo. Part of the Syrian/Egyptian connection is related in the Old Testament in the book of Daniel XI-6.
