Corona Borealis (pronounced /kəˈroʊnə ˌbɒriˈælɪs/, Latin: northern crown) is a small northern constellation whose main stars form a semicircular arc. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. This is about the direction for other uses see North (disambiguation. A crown is the traditional Symbolic form of Headgear worn by a Monarch or by a Deity, for whom the crown traditionally represents power In common usage a constellation is a group of celestial bodies that are connected together in some arrangement typically stars to form a visible figure or picture A star is a massive luminous ball of plasma. The nearest star to Earth is the Sun, which is the source of most of the Energy on Earth It is one of the 88 modern constellations, and was also one of the 48 constellations listed by Ptolemy, who referred to the constellation as Corona. Claudius Ptolemaeus ( Greek: Klaúdios Ptolemaîos; after 83 &ndash ca The Borealis (northern) was added later on, to contrast with Corona Australis, the southern crown. Corona Australis ( or Corona Austrina ( Southern crown) was one of Ptolemy 's 48 Constellations and also counts among the 88 modern

Notable features
It has no first magnitude stars. Its brightest star, α CrB (Alphecca, also known as Gemma) is of magnitude 2. Alpha Coronae Borealis (α CrB / α Coronae Borealis is a Binary star in the Constellation Corona Borealis. 2 (slightly variable) and is considered a member of the diffuse Ursa Major Moving Group. For the astronomical object see Variable star. Variable Star is a 2006 novel written by Spider Robinson The Ursa Major Moving Group, also known as Collinder 285, is the closest Moving group to Earth, that is a set of stars with common velocities in space The constellation contains several interesting variable stars: two of the best known are R Coronae Borealis and T Coronae Borealis. R Coronae Borealis is a yellow Supergiant star and is the prototype of the RCB class of Variable stars which fade by several magnitudes T Coronae Borealis, informally nicknamed the Blaze Star, is a recurring Nova in the Constellation Corona Borealis.
Notable deep sky objects
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. Galaxy groups and clusters are the largest Gravitationally bound objects to have arisen thus far in the process of cosmic structure formation The apparent magnitude ( m) of a celestial body is a measure of its Brightness as seen by an observer on Earth, normalized to the value

Mythology
Corona Borealis was sometimes considered to represent a crown that was given by Dionysus to Ariadne, the daughter of Minos of Crete. In Classical mythology, Dionysus or Dionysos (in Greek, Διόνυσος or Διώνυσος; associated with Roman Ariadne, in Greek mythology (Latin Arianna French Arianne was daughter of King Minos of Crete and his queen Pasiphaë, daughter In Greek mythology, Minos ( Ancient Greek:) was a mythical king of Crete son of Zeus and Europa. At other points it was considered to belong, in a sense, to Boötes, the herdsman, or the keeper of the bears. Boötes ( Greek Βοώτης or herdsman) is one of the 88 modern Constellations and was also one of the 48 constellations listed by Ptolemy. The Cheyenne tribe called it "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). Welsh mythology, the remnants of the Mythology of the pre Christian Britons, has come down to us in much altered form in medieval Welsh manuscripts Arianrhod is a figure in Welsh mythology who plays her most important role in the Fourth Branch of the Mabinogi.
