Excerpt: Cepheus is a constellation in the northern sky. It is named after Cepheus, King of Aethiopia in Greek mythology, and is considered to represent a king. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations. γ Cephei is a binary star approximately 50 light years away from Earth. The system consists of an orange subgiant and a red dwarf. Due to the precession of the equinoxes, γ Cephei will be the pole star between AD 3000 and 5200, with the closest approach to the celestial pole around AD 4000. The primary component is orbited by a planet. δ Cephei is the prototype Cepheid variable. It was discovered to be variable by John Goodricke in 1784. It varies between 3.5 and 4.3 over a period around 5.4 days. There are three red giants in the constellation that are visible to the naked eye. The first, μ Cephei, is also known as Herschel's Garnet Star due to its deep red colour. It is a semiregular variable star that varies between 3.4 and 5.1 over a period of 730 days. The star is around 11.8 AU in radius. If it were placed at the centre of our Solar System, it would extend to the orbit of Saturn. The second, VV Cephei, is also variable and ranges from 4.8 and 5.4 over...
