Left: LO-IV-074H Overhead view from [/Lunar%20Orbiter Lunar Orbiter]. The 13-km diameter circular crater on Cepheus' northeast rim is Cepheus A. In addition to its central peaks, Cepheus appears to have a 5-km diameter depression (a relatively fresh impact crater?) at its center.
Right: Damian Peach, April 16, 2006 An Earth-based view showing a small peak to the northeast of Cepheus' center. This appears to be at the end of a ridge, common to the two photos and just north of the feature casting the strong westward shadow in the Lunar Orbiter view.

Description
Description: Elger
([/IAU%20Directions IAU Directions]) CEPHEUS.--A peculiarly shaped ring-plain, 27 miles in diameter. The W. border is nearly rectilineal, while on the E., the wall forms a bold curve. There is a very brilliant crater on the summit of this section, and a central mountain on the floor. The E. wall is much terraced. E. of Cepheus, close to the brilliant crater, there is a cleft or narrow valley running N. towards [/Oersted Oersted].

Additional Information
- Depth data from [/Kurt%20Fisher%20crater%20depths Kurt Fisher database]
- Westfall, 2000: 4.59 km
- From the shadows in LO-IV-067H and LO-IV-074H, Cepheus A is 2710-2780 m deep. The shadow cast by the feature to the east of Cepheus' center spans a height range of a little over 800 m. This appears to be cast by a very low hill into the pit of a relatively fresh central crater; but the observed effect might conceivably be created by an arrangement of central peaks with irregular slopes. - JimMosher JimMosher
- Satellite crater Cepheus A is on both the [/ALPO%20list%20of%20bright%20ray%20craters ALPO list of bright ray craters] and the [/ALPO%20list%20of%20banded%20craters ALPO list of banded craters]

Nomenclature
- Named for Cepheus, a Greek [/Nomenclature-Mythological%20Figures mythological astronomer], ruler of the Phoenician nation of Aethiopia and the father of Andromeda.
- According to [/Whitaker Whitaker] (p. 211), the name Cepheus was introduced on [/Riccioli Riccioli]'s map (from which much of the original [/IAU%20nomenclature IAU nomenclature] derives), however the feature so-designated was what we now call [/Franklin Franklin]. The present crater was not named on Riccioli's map.
- [/Johann%20Schr%C3%B6ter Johann Schröter] (in his Plate VII) labeled [/Franklin Franklin] as Cepheus austral. and called the present crater Cepheus boreal..
- By the time Mary Blagg's [/Collated%20List Collated List] was issued (1913) all three of her authorities used the names Cepheus and Cepheus A with their modern meanings.
- The names Cepheus and Hercules are the only two in the gazetteer of official lunar nomenclature which are also the names of constellations in the celestial northern hemisphere.- DannyCaes DannyCaes Apr 25, 2010
Cepheus E or Cepheus Epsilon?
- SLC-B2 shows some sort of mountain or hill about halfway between Cepheus and Maury. It is labeled "E" with and arrow pointing toward Cepheus. The ACT-REACT Quick Map of the LROC site doesn't show an "E" at that location, or... should it be Epsilon? (Cepheus Epsilon?). - DannyCaes DannyCaes Feb 12, 2017
- Chart 21 in the Times Atlas of the Moon shows, at that location, a rather large non-circle shaped region called Cepheus E.
