Hertzsprung is an enormous lunar impact crater, or impact basin, that is located on the far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin. Nearby craters of note include Michelson across the northeast rim, Vavilov across
H. G. Wells is a lunar impact crater that is located on the far side of the Moon, behind the northeastern limb. It lies to the south of the crater Millikan, and to the northeast of Cantor. Just to the southeast is the smaller Tesla. The crater is named after the author H. G. Wells whose works include the 1901 novel The First Men in the Moon. This
Hippocrates is a lunar impact crater on the far side of the Moon. It is located in the northern region of the lunar surface, to the north of the crater Stebbins. To the southwest of Hippocrates are Kirkwood and the large Sommerfeld. This is a relatively old formation that has become worn and eroded due to subsequent impacts. The general outline of the outer rim is
Houzeau is a lunar impact crater on the far side of the Moon. It is located to the northwest of the Mare Orientale impact basin, and ejecta from that event has fallen across this crater rim and its interior. To the south of Houzeau lies the crater Gerasimovich, and one crater diameter to the west is Belopol’skiy. To the northwest lies Fridman, with Ioffe to its southwest. The perimeter
Icarus is a lunar impact crater that lies on the Moon’s far side. It is located to the west of the huge walled plain Korolev, and less than two crater diameters to the east of the crater Daedalus. To the south of Icarus is the smaller Amici. Icarus has a worn rim and a relatively wide inner wall. A small crater lies across the
Ioffe is a lunar impact crater on the far side of the Moon. It lies to the south of the walled plain Hertzsprung, and is attached to the southwestern outer rim of Fridman. Only a short stretch of terrain separates Ioffe from Belopol’skiy to the southeast. This is a relatively youthful crater, with a well-defined outer rim and a terraced inner wall. Nevertheless, the outer rim has been marked by
Izsak is a small lunar impact crater that is located on the Moon’s far side, hidden from view from the Earth. It lies about half-way between the walled plains Fermi to the northeast and Milne to the southwest. Due south of Izsak is the larger crater Schaeberle. Izsak is a circular, nearly symmetric crater formation with a sharp-edged rim that has received little erosion. At the midpoint
Gullstrand is a lunar impact crater that lies on the northern hemisphere on the Moon’s far side. About one crater diameter to the southeast is the larger crater Perrine. To the west-southwest is Quetelet. This crater has a circular rim that is relatively well-defined, and has only been moderately worn. A small, bell-shaped crater forms a break through the rim to the southwest, and a
Gerasimovich is a lunar impact crater on the far side of the Moon. It lies beyond the western limb, to the west-northwest of the immense Mare Orientale impact basin. The outer blanket of ejecta from this impact reaches nearly to the rim of Gerasimovich. Nearby craters of note include Houzeau to the north and the smaller Ellerman to the southeast. The outer rim of this crater is worn
Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe. This crater lies in the southern part of the ejecta blanket that encircles Hertzsprung, and in the west-northwestern part of the huge ejecta blanket surrounding the Mare Orientale impact
