The orange hypergiant, RW Cephei, is one of the largest stars known to the human race. Mu Cephei is a prototype for a class of stars known as the Mu Cephei variables. Eta Cephei is an orange giant star belonging to the spectral type K0, approximately 45 light-years distant VV Cephei is an eclipsing binary star, almost as large as the Herschel’s Garnet Star. Phineus and his followers asked that Andromeda be turned over to them, but Cepheus refused them and there was a fight. This constellation inherited its name after the mythical king of Ethiopia. Alderamin is the brightest star in the Cepheus constellation. The star system is only 13.15 light-years (4.03 parsecs) distant. Cepheids typically form with masses 3-30 times that of the Sun, then pass through the main sequence stage as B-class stars and, once they have burnt up the hydrogen in their core, their helium core loses stability and begins to contract and expand at regular intervals and they undergo stages of nuclear burning. NGC 7142 is another open cluster in Cepheus. Gamma Cephei is classified as an orange subgiant (spectral type K1III-IV) and is believed to be 6.6 billion years old. For a better understanding of its massive size, if we place this Garnet Star in our sun’s position, it would reach somewhere between the orbit of Jupiter and Saturn. The precession of the equinoxes is shifting the pole ever-closer to the boundary between the two constellations, and by 7500 AD, Cepheus's brightest star Alderamin will have become the pole star. Alfirk is the second brightest, with a magnitude of 3.15. Das Doppelsystem ist etwa 4900 Lichtjahre von unserer Erde entfernt. The brightest stars of this high northern constellation form a pattern resembling a childs drawing of a house and are easly ignored among their more obvious and prominent neigbours. Q. Zeus placed him in the sky after his tragic death because he was descended from one of Zeus’ loves, the nymph Io. The star’s spectral type varies from F5 to G3 over a period of 5.36634 days (5 days, 8 hours, 47 minutes and 32 seconds). The star Delta Cephei gave its name to the variable Martin Snodin 119,120 views Main Stars: Cepheus consists of 7 main stars. The cluster is located with the Milky Way Galaxy and is approximately 7,000 light years distant from the solar system.
