Cepheus OB6

Along with Delta Cep, Zeta appears to be part of the Cepheus OB6 association (centered at 880 light years), an expanding group of massive stars that share a common birthplace.
Finally, δ Cephei is usually considered to be a member of the loose association Cepheus OB6 (de Zeeuw et al. 1999; van Leeuwen et al. 2007; Majaess et al. 2012).

Delta Cephei (stars.astro.illinois.edu) DELTA CEP (Delta Cephei). Surely among the most famed of all stars, fourth magnitude (4.1 or thereabouts) Delta Cephei, set at the southeastern corner of dim Cepheus (the King), does not even have a proper name. It is, however, the only star that has given its constellation name over to represent a whole class of stars, the “Cepheids.”

Wikipedia

Delta Cephei (Wikipedia) Delta Cephei (δ Cep, δ Cephei) is a quadruple star system located approximately 887 light-years away in the northern constellation of Cepheus, the King. At this distance, the visual magnitude of the star is diminished by 0.23 as a result of extinction caused by gas and dust along the line of sight. It is the prototype of the Cepheid variable stars that undergo periodic changes in luminosity.
