Description


Description: Elger

(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.

Cepheus

Additional Information

  • Depth data from 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. - Jim Mosher
  • Satellite crater Cepheus A is on both the ALPO list of bright ray craters and the ALPO list of banded craters
  • TSI = 30, CPI = 15, FI = 20; MI =65 Smith and Sanchez, 1973


Nomenclature

  • Named for Cepheus, a Greek mythological astronomer, ruler of the Phoenician nation of Aethiopia and the father of Andromeda.
  • According to Whitaker (p. 211), the name Cepheus was introduced on Riccioli's map (from which much of the original IAU nomenclature derives), however the feature so-designated was what we now call Franklin. The present crater was not named on Riccioli's map.
  • Johann Schröter (in his Plate VII) labeled Franklin as Cepheus austral. and called the present crater Cepheus boreal..
  • By the time Mary Blagg's 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 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 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.
