It is one of the 48 constellations listed by the second century astronomer Ptolemy, and it remains one of the 88 constellations in the modern times. The constellation's brightest star is Alderamin (Alpha Cephei), with an apparent magnitude of 2.5. Delta Cephei is the prototype of an important class of star known as a Cepheid variable.

Map showing location of NGC 6939. NGC 6939 is located near the border of the constellations Cepheus and Cygnus, at the southwest corner of Cepheus.The open cluster is located two degrees southwest of Eta Cephei and 2/3° northwest from the spiral galaxy NGC 6946, which has visual magnitude 8.7.
NGC 7354 is a planetary nebula located in the northern circumpolar constellation of Cepheus, at a distance of approximately 5.5 kly from the Sun. [2] It was discovered by German-born astronomer William Herschel on November 3, 1787.
Delta Cephei (δ Cep, δ Cephei) is a quadruple star system [4] 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.

NGC 7419 is an open cluster in the constellation Cepheus. It is heavily reddened and notable for containing five red supergiants, the highest number known in any cluster until the end of the 20th century, but probably no blue supergiants.
W Cephei is a spectroscopic binary and variable star located in the constellation Cepheus. It is thought to be a member of the Cep OB1 stellar association at about 8,000 light years. [5] [11] The supergiant primary star is one of the largest known stars and as well as one of the most luminous red supergiants.
Eta Cephei (η Cep, η Cephei) is a star in the northern circumpolar constellation of Cepheus.With an apparent visual magnitude of 3.4, [2] this is a third magnitude star that, according to the Bortle Dark-Sky Scale, is readily visible to the naked eye.
