One of the constellations that is considered to be a circumpolar constellation is Cepheus.
This indicates that it is located close to the north celestial pole and may be seen at any time of the year. at least in the hemisphere’s northern half.
Cepheus rules over the fabled land of Ethiopia, which has nothing to do with the modern-day African nation of the same name.
He is the father of the stunning Princess Andromeda, whom he shares with his arrogant and pompous wife, Queen Cassiopeia. The sea nymphs were insulted by Cassiopeia’s assertions that she possessed the greatest beauty.
Poseidon, the god of the sea, despatched a sea monster to attack her country and its inhabitants.
After consulting the Oracle, King Cepheus learned that the only way to save his kingdom and the people who lived there was to give up his daughter Andromeda as a sacrifice.
Andromeda was restrained by her chains on a rock close to the coast, and then she was abandoned for the monstrous Cetus.
However, as chance would have it, Perseus was passing by shortly after he had finished off the Gorgon Medusa.
Perseus was able to rescue Andromeda and later become her husband
Finding The Kingdom Of Constellation Cepheus
The form of the constellation Cepheus resembles a square with a triangle protruding from the top. In the previous picture, you can also make out a portion of Lacerta.
Position in the sky:
Right Ascension: 22 hours
Declination: 70 degrees
Visible between latitudes 90 and -10 degrees
Best seen in October (at 9:00 PM)
named stars: Alderamin(Alpha Cep),Alfirk(Beta Cep) ,Alrai(Gamma Cep),Herschel’s “garnet star” (Mu Cep), Alkurhah (Xi Cep) ,Al kalb al rai (Rho 2 Cep)
Although Cepheus is not a particularly brilliant constellation, it is situated in a rather vacant section of the sky close to the North Pole, which makes it quite easy to detect.
Located between the constellations Ursa Minor and Camelopardalis. In addition, Cepheus is flanked on both sides by his queen, the pompous Cassiopeia, and Draco, the constellation of the dragon. The constellations Cygnus and Lacerta can be found directly beneath Cepheus.
There are three star systems known as Kappa, omicron, and pi Cephei.
The common name for Nu Cephei is Cor Regis, which derives from the Latin phrase “heart of the king.” It is difficult to see with the human eye because it has a magnitude of 5, but viewing it using binoculars is a real delight.
It is possible to see with the unaided eye three of the red supergiant stars that are contained inside the constellation.
The open cluster known as NGC 188 holds the title of being the open cluster that is located at the location in the sky that is the closest to the north celestial pole. in addition to being one of the earliest open clusters that is known.
The Fireworks Galaxy, also known as NGC 6946, is a spiral galaxy that has been found to contain nine supernovae, which is more than any other galaxy has ever been found to contain.
The most massive protostar that has been found to date can be found within the nebula designated as NGC 7538.
The star Delta Cephei is considered to be the progenitor of what are now known as Cepheid variable stars. The study of stars like this allows astronomers to more accurately calculate distances.
Cepheus is home to three of the five brightest and most massive stars that are known to exist.
Herschel’s Garnet Star is the name commonly given to Mu Cephei. It is one of the largest stars that we are aware of, and it has a red supergiant classification. Only three other stars, VV Cephei A and V354 Cephei, are known to be bigger than mu Cephei, and both of these stars are located in the same constellation.
If it were to exist in our solar system, the circumference of V354 Cephei, measured in astronomical units (AU), would stretch from the location of the Sun to beyond the orbit of Jupiter. V354 Cephei is the third-largest star ever discovered.
However, VV Cephei A is the king of the hill; with a mass that is approximately 2,000 times that of our Sun, it is the most massive star that has ever been measured (it would swallow up Saturn).
