Corona Borealis is a small constellation in the northern sky. Its name is Latin for "northern crown", a name inspired by its shape; its main stars form a semicircular arc. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy and remains one of the 88 modern constellations.

Corona Borealis contains no bright deep sky objects. Abell 2065 is a highly concentrated galaxy cluster containing over 400 members, the brightest of which are of 16th magnitude.
Corona Borealis was sometimes considered to represent a crown that was given by Dionysus to Ariadne, the daughter of Minos of Crete.[citation needed] At other points it was considered to belong, in a sense, to Boötes, the herdsman.[citation needed] The Cheyenne nation of Native Americans called it the "Camp Circle" as they arranged their camps in a semicircle. In Welsh mythology, the Northern Crown was called Caer Arianrhod, ‘the Castle of the Silver Circle,’ and was the heavenly abode of the Lady Arianrhod (Squire, 2000:154-155).
