He was married to Cassiopeia and was the father of Andromeda, both of whom are immortalized as modern day constellations along with Cepheus.

[9] Delta Cephei is a yellow-hued supergiant star 980 light-years from Earth and the prototype of the class of the Cepheid variables.

Mu Cephei is also known as Herschel's Garnet Star due to its deep red colour.

The second, VV Cephei A, is a semiregular variable star, located approximately 5,000 light-years from Earth.

[14] It is part of a triple star system similar to VV Cephei,[17][18] and has a diameter 980 times that of the Sun.

[19] All four stars have initial masses more than eight times that of the Sun and are accepted core-collapse supernova candidates.

Xi Cephei is another binary star, 102 light-years from Earth, with a period of 4,000 years.

[23] Cepheus is most commonly depicted as holding his arms aloft, praying for the deities to spare the life of Andromeda.

[4] In Chinese astronomy, the stars of the constellation Cepheus are found in two areas: the Purple Forbidden enclosure (紫微垣, Zǐ Wēi Yuán) and the Black Tortoise of the North (北方玄武, Běi Fāng Xuán Wǔ).
