Hell (crater)
Hell is a lunar crater in the south of the Moon's near side, within the western half of the enormous walled plain Deslandres. To the southeast, also within Deslandres, is the larger crater Lexell, and about 9° to the south lies the prominent Tycho crater.〔 The crater received its name in 1935 after the Hungarian astronomer and ordained Jesuit priest Maximilian Hell.〔 It has 19 satellite craters with diameters ranging between about 3 and 22 km. Nearly all Hell craters are relatively flat and shallow, with a sharp, well-defined rim and a typical diameter-to-depth ratio of about 10.
==Description==
Hell is somewhat circular but with an outward bulge along the western rim. The interior floor is rolling and uneven, with a several hills and a central peak about 1 km tall.〔(Hell ), May 24, 2010〕〔Naosuke Sekiguchi, 1972. Catalogue of Central Peaks and Floor Objects of the Lunar Craters on the Visible Hemisphere. University of Tokyo Press and University Park Press ISBN 0-8391-0649-1〕 The sharp-edged rim is not significantly eroded, and has a narrow inner wall; it is 2–3 times higher on the north-west than on the east where it rises by about 820 meters.〔Edmund Neville Nevill (The moon, and the condition and configurations of its surface ), Longmans, Green, and Co., 1876, p. 371〕
