DescriptionThe two Hunting Dogs — named Asterion ('starry') and Chara ('joy') — were added by Johannes Hevelius in 1687, depicted being held on a leash by Boötes as he drives the Great Bear around the pole. The constellation contains one of the finest globular clusters in the northern sky, M3, home to roughly 500,000 stars about 34,000 light-years away. Its brightest star, Cor Caroli ('Heart of Charles'), was named by Edmund Halley to honor King Charles I of England; it is the prototype of a class of chemically peculiar magnetic stars whose brightness varies as they rotate.
