The boast of Cassiopeia was that both she and her daughter Andromeda were more beautiful than all the Nereids, the nymph-daughters of the sea god Nereus.

The Queen Cassiopeia, wife of king Cepheus of Æthiopia, was beautiful but also arrogant and vain these latter two characteristics led to her downfall. Once you have located a sky object on the planisphere, you can locate it easily in the night sky.Poseidon's punishment: Cassiopeia as a constellation sitting in the heaven tied to a chair. A planisphere lets you see the stars as you might see them in the sky. A planisphere contains a movable disk with an orifice through which you can observe a portion of the sky. You may also use the aid of a planisphere, which is a map of the stars and constellations. You can find Cassiopeia in the night sky locating the Big Dipper, which is another circumpolar asterism in the sky, and then trace an imaginary line from the bowl´s outer stars all the way to Polaris and continue ahead another similar distance. Another recognizable feature of Cassiopeia is that is situated at the same distance that the Big Dipper is situated from Polaris, although in the opposite direction. it is also recognized because it lies on the band of the Milky Way and contain many deep sky objects and other dim stars within. How do you recognize Cassiopeia in the sky?Ĭassiopeia is best recognized in the night sky by its bright stars that form the shape of a w. Cassiopeia lies between the constellations Andromeda to the south and Cepheus to the north. This constellation also is situated about 30 degrees south of Polaris. Cassiopeia is between 0-2 hours right ascension and between 55 and 65 degrees declination. The constellation Cassiopeia is a circumpolar constellation, that is to say, it is located close to Polaris, the North Star and can be seen throughout most of the year in the night sky in the northern latitudes. NGC 457, which contains more than one hundred stars, was discovered in 1787 by William Herschel. One called Tycho´s Star, which was observed by Tycho Brahe in 1572 the other known as Cassiopeia A, a bright radio source supernova remnant. Cassiopeia contains two supernova remnants. Both of these Messier objects are open clusters, containing several stars each. The constellation Cassiopeia contains some deep sky objects known as messier objects, including M52 and M103. The constellation Cassiopeia contains a number of fainter stars, all which can be detected with high resolution telescopes.

These include Alpha Cassiopeia, which is a double star of magnitude 2.2 Beta Cassiopeia, which is a white star with magnitude 2.3 Gamma Cassiopeia, which is a variable star, with a minimum magnitude of 3.0 and a maximum magnitude of 1.6 and Delta Cassiopeia, which is an eclipsing star with variable magnitudes of between 0.1 and 2.7.

The five stars forming Cassiopeia are all above third magnitude. The constellation Cassiopeia was named after the queen of Ethiopia. Cassiopeia contains some interesting deep sky objects and many stars. Given there are clear skies, Cassiopeia can be seen high in the sky throughout much of the year. Cassiopeia is best recognized by its resemblance to the letter w or M, depending on the time of the year.

Cassiopeia is one of the 88 constellations that have been classified in the night sky.
