Constellation Cepheus (King)
Properties
The constellation Cepheus revolves around the celestial north pole, followed by Cassiopeia on its eastern side and stands for Central Europe in the sky all year round. Despite its importance in Greek mythology, Cepheus is a less prominent constellation to the naked eye. In a dark sky you can see a figure that resembles a child's drawing of a house with a gable roof. The southern part of the constellation stands in a branch of the band of the Milky Way. The area is 588 square degrees and the center culminates on September 29 at midnight. Cepheus contains one of the most important variable stars for modern astronomy: delta Cephei. [9, 15]

Mythology and History
The constellation symbolizes Cepheus, the king of Ethiopia. He descended from Belos, the legendary Assyrian king. Cepheus' wife was the vain Cassiopeia, who boasted of being more beautiful than the nymphs of the sea. As punishment for Kassiopeia's vanity, the pretty princess Andromeda - daughter of this royal family in the sky - was chained to a rock by the sea to be sacrificed to the whale Cetus. The hero Perseus rode up through the air on Pegasus, freed Andromeda and married her. [82]
