The sky is not divided up equally between the constellations. Cepheus takes up 587.787 sq. degrees of the night sky which equates to 1.42% of the night sky. The constellation gets its name as it name means King of Ethiopia . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

The brightest star in Cepheus is Alderamin. There are 3 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Cepheus. The current largest star so far identified in the constellation of Cepheus is RW Cephei. For a list of named stars, that is stars that don't start HD or HIP, please visit Cepheus Star List Page.
The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Cepheus is 1885. The number of stars that are of magnitude 6.0 or lower in the constellation is 95. The number of stars in the constellation that make up the outline is 5.
There are no deep space objects that were identified by Charles Messier in this constellation. There are 1 non-Messier deep space objects that are covered on this site and the list is below.
The nearest star to Earth is Kruger 60 which is roughly about 13.05 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HIP 109384 which is about 182.83 Light Years. The furthest star that can be located in the constellation is HIP 104589 which is located about 326163.3 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The dimmest star that can be seen in Cepheus with the naked eye is HD 202987. The dim star has an apparent magnitude of 6. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan
The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
