(IAU Directions) SHARP.--A ring-plain somewhat smaller than Mairan, on the W. of the Sinus Iridum, from the coast-line of which it is separated by lofty mountains. There is a distinct crater at the foot of its N.W. wall, and a bright central mountain on the floor. On the N. is a prominent enclosure, nearly as large as Sharp itself; and on the N.W. a brilliant little ring- plain, A, about 8 miles in diameter, connected with Sharp, as Madler shows, by a wide valley.

Additional Information
- Depth data from Kurt Fisher database
- Westfall, 2000: 3.84 km
- Viscardy, 1985: 3.2 km
- From the shadows in LO-IV-158H, the terrace along the upper east rim of Sharp is 1700-2700 m tall. Obviously, the crater as a whole is deeper than that. - JimMosher
- Sharp B
- Satellite crater Sharp B is on the ALPO list of bright ray craters.
- Central ridge heights
- Sekiguchi, 1972: 0.3 km - fatastronomer
- TSI = 30, CPI = 20, FI = 20; MI =70 Smith and Sanchez, 1973
Nomenclature
- Named for Abraham Sharp (1651-1742), a British astronomer and mathematician.
- According to Whitaker (p. 218), this name was introduced (in the form Sharpius) by Schröter. As Whitaker notes, Schröter was using a name he had found on a list prepared by Hell, and apparently used by Hell for the same feature (p. 93).
- Crater Sharp B was called Aymat by Hugh Percy Wilkins and Paluzie-Borrel (see the book The Moon by H.P.Wilkins and P.Moore), but the I.A.U. did not accept that name. Aymat (Antonio Aymat Mareca) was a Spanish astronomer.
- Sharp Xi (hill southwest of Foucault Beta, altogether with the nearby hill Foucault Gamma sometimes called Montes Foucault). See Chart 7 in the Times Atlas of the Moon.

A curiosity...
This is not at all related to Abraham Sharp and/or the nearside crater officially known as Sharp, but... perhaps it's quite interesting to know :
A certain Robert P. Sharp is mentioned on page 395 of Mysterious Universe, a handbook of astronomical anomalies (William R. Corliss, The Sourcebook Project, 1979), as co-author of the article Channels on Mars (together with Michael C. Malin, Bulletin of the Geological Society of America, 1975). - DannyCaes Apr 19, 2015
