Marconi is a lunar impact crater that is located on the Moon's far side. It lies to the northwest of the large walled plain Gagarin, and to the southwest of the prominent crater Chaplygin. To the west-northwest of Marconi is the slightly larger Dellinger.
This is a well-formed crater with only some modest impact erosion that has softened the features. The outer rim is marked only by a few tiny craterlets and some terrace structures can still be seen along the inner walls. There is a pair of small craterlets along the inner wall to the south and east. Near the midpoint of the relatively level interior floor is a low central rise composed of several small hills. The floor is otherwise marked by a number of tiny craterlets.
The crater was named after Italian physicist, inventor, and Nobel laureate Guglielmo Marconi by the IAU in 1970. [1] The crater was known as Crater 295 prior to naming. [2]
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Marconi.

Armiński is a small lunar impact crater that is located on the far side of the Moon, to the northeast of the large walled basin Gagarin. To the northwest of Armiński is the crater Beijerinck, and to the southeast lies Cyrano.
Bose is a lunar impact crater that is located on the far side of the Moon, in the southern sphere hemisphere. It lies just to the northwest of the smaller crater Bhabha, and southeast of Alder.
Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.
Boole is a lunar impact crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has been worn and rounded due to subsequent impacts. It is named after George Boole.
Rost is a lunar impact crater that is located in the southwestern part of the Moon, to the southeast of the elongated formation Schiller. To the southeast of Rost is the larger crater Scheiner. West-southwest of this formation is the smaller Weigel.
Breislak is a lunar impact crater that lies within one crater diameter north-northwest of the crater Baco, in the southern part of the Moon. To the north-northwest is the crater Barocius, and to the west lies Clairaut. This crater was named in honor of geologist Scipione Breislak.
Lemaître is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the south of the older crater Minkowski, and north of Crommelin. To the east-southeast lies the crater Eijkman.
Helmholtz is a lunar impact crater, approximately 110 kilometers in diameter, that is located near the south-southeast limb of the Moon. Attached to the south-southeast rim of Helmholtz is the somewhat smaller crater Neumayer. The larger crater Boussingault is nearly attached to the west-southwestern rim. The crater is named after German physicist and physician Hermann von Helmholtz
Cori is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies less than one crater diameter to the north of the crater Baldet. To the northeast is the crater Grissom. It is named after Gerty Cori, the first American woman to win the Nobel Prize and the first woman to win the prize in the category Nobel Prize in Physiology or Medicine.
Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.
Leibnitz is a huge lunar impact crater that is located in the southern hemisphere on the far side of the Moon. This formation is the same size as Clavius on the near side. It is located to the east-southeast of Mare Ingenii, and is joined to the northeast rim of Von Kármán. Attached to the eastern rim of Leibnitz is Davisson, and intruding into the southeast rim is Finsen. Farther to the west is the large Oppenheimer.
Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.
Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge walled plain Mendeleev, about midway between the craters Schliemann to the northeast and Marconi to the southwest. It is about the same size as Albategnius on the near side.
Einthoven is a lunar impact crater that is located on the far side of the Moon. It is located beyond the region of the surface that is sometimes brought into view due to libration, and so can not be viewed from the Earth. Einthoven is located to the northeast of the huge walled plain Pasteur.
Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.
Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.
Ganskiy is a lunar impact crater that is located on the far side of the Moon. It lies to the southeast of the walled plain Hirayama.
Nöther is a lunar impact crater on the far side of the Moon. It is located in the far northern latitudes, to the northwest of the walled plain Poczobutt. About two crater diameters to the north-northwest of Nöther lies Niepce.
Ostwald is a lunar impact crater on the far side of the Moon. It lies just to the east of the crater Guyot, and near the northern border of Ibn Firnas. Recht lies along its eastern rim.
Schuster is a lunar impact crater that lies along the eastern rim of the much larger walled plain Mendeleev, on the far side of the Moon. To the east of Schuster is the crater Henderson, and to the southeast lies the large Chaplygin.
