Description

Another circumpolar constellation is the Ethiopian king, Cepheus (SEE-fee-us). He sits atop the Milky Way on a throne near his queen Cassiopeia. The legs and seat of his throne make a rough square. On the Ursa Major side of Cassiopeia, looks like a house (or throne) sitting on the Milky Way. Look for mu-Cephei, the "garnet star," with a deep reddish tint. The back of the seat comes to a point at the top above his head.

Special Stars

D-Cephei, pulsating giant star.

The Garnet Star is one of the reddest stars known. A huge red giant, much like Betelguese in Orion, its size is uncertain, but if its center were where our sun is, we would be inside it.

The brightest star in Cepheus is Alderamin. In 5000 years it will become the pole star, as it was in 18,000 B.C. (see discussion of precession under Lyra).
