![]() The charioteer's whip was represented by Gamma Cassiopeiae, sometimes called "Tsih", the Chinese word for "whip". Kappa, Eta, and Mu Cassiopeiae formed a constellation called the Bridge of the Kings when seen along with Alpha and Beta Cassiopeiae, they formed the great chariot Wang-Liang. The Chinese astronomers saw several figures in what is modern-day Cassiopeia. In Chinese astronomy, the stars forming the constellation Cassiopeia are found among three areas: the Purple Forbidden enclosure (紫微垣, Zǐ Wēi Yuán), the Black Tortoise of the North (北方玄武, Běi Fāng Xuán Wǔ), and the White Tiger of the West (西方白虎, Xī Fāng Bái Hǔ). This depiction is from Augustin Royer's 1679 atlas. In France, she was portrayed as having a marble throne and a palm leaf in her left hand, holding her robe in her right hand. In Persia, she was drawn by al-Sufi as a queen holding a staff with a crescent moon in her right hand, wearing a crown, as well as a two-humped camel. Ĭassiopeia has been variously portrayed throughout her history as a constellation. Andromeda was then rescued by the hero Perseus, whom she later married. ![]() She was forced to wheel around the north celestial pole on her throne, spending half of her time clinging to it so she does not fall off, and Poseidon decreed that Andromeda should be bound to a rock as prey for the monster Cetus. She was placed in the sky as a punishment after enraging Poseidon with the boast that her daughter Andromeda was more beautiful than the Nereids or, alternatively, that she herself was more beautiful than the sea nymphs. Cepheus and Cassiopeia were placed next to each other among the stars, along with Andromeda. Cassiopeia was the wife of King Cepheus of Aethiopia and mother of Princess Andromeda. The constellation is named after Cassiopeia, the queen of Aethiopia. IC 10 is an irregular galaxy that is the closest known starburst galaxy and the only one in the Local Group of galaxies.Ĭassiopeia in her chair, as depicted in Urania's Mirror A rich section of the Milky Way runs through Cassiopeia, containing a number of open clusters, young luminous galactic disc stars, and nebulae. Fourteen star systems have been found to have exoplanets, one of which- HR 8832-is thought to host seven planets. Cassiopeia A is a supernova remnant and the brightest extrasolar radio source in the sky at frequencies above 1 GHz. ![]() In 1572, Tycho Brahe's supernova flared brightly in Cassiopeia. ![]() The constellation hosts some of the most luminous stars known, including the yellow hypergiants Rho Cassiopeiae and V509 Cassiopeiae and white hypergiant 6 Cassiopeiae. In the (sub)tropics it can be seen at its clearest from September to early November, and at low southern, tropical, latitudes of less than 25°S it can be seen, seasonally, low in the North.Īt magnitude 2.2, Alpha Cassiopeiae, or Schedar, is generally the brightest star in Cassiopeia, though it is occasionally outshone by the variable Gamma Cassiopeiae, which has reached magnitude 1.6. It is easily recognizable due to its distinctive ' W' shape, formed by five bright stars.Ĭassiopeia is located in the northern sky and from latitudes above 34°N it is visible year-round. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. Visible at latitudes between + 90° and − 20°.īest visible at 21:00 (9 p.m.) during the month of November.Ĭassiopeia ( listen) is a constellation in the northern sky named after the vain queen Cassiopeia, mother of Andromeda, in Greek mythology, who boasted about her unrivaled beauty. for the constellation also / ˌ k æ s i ˈ oʊ p i ə/ Cássiópeia ![]()
