Cremona is a lunar impact crater that is located along the north-northwestern limb of the Moon. From the Earth this crater is viewed from the side, and the visibility is affected by libration effects. To be viewed in any detail, this crater must be seen or photographed from orbit. It is located midway between the crater Boole to the south-southeast and, on the far side of the Moon, the crater Lindblad.
This is a relatively old, worn crater that is overlaid by a number of smaller craters. The rim has been worn down and rounded by lesser impacts, leaving only a wide depression in the surface with somewhat irregular interior walls. Small craters lie across the north and northwestern rims, and the satellite crater Cremona L is laid across the southern rim. A band of tiny craterlets lies across the northeastern part of the rim, continuing part of a pattern of multiple craterlets that continue to the north.
The craters Cremona B and C form a double-crater pair in the northwestern part of the floor. The inner wall on the western side is unusually wide, forming a rough interior surface. The floor in the eastern half is more level, and contains the remnant of a central peak attached to the eastern rim of Cremona C.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Cremona.

Crommelin is an ancient lunar impact crater that is located in the vicinity of the south pole of the Moon, on the far side. It lies to the north of the large crater Zeeman, and to the east-northeast of Numerov.
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.
Brianchon is a lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit.
Lindblad is an old lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb. This formation is located to the southeast of the crater Brianchon, and northeast of Cremona.
Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.
Belopol'skiy is a lunar impact crater that is located on the far side of the Moon. It lies to the west of the crater Houzeau, and northeast of Strömgren. Just to the northwest of Belopol'skiy is the crater Ioffe.
Cannizzaro is a lunar impact crater that is located on the Moon's far side as seen from the Earth, just beyond the northwestern limb. It lies in a region of the surface that is sometimes brought into view due to the effects of libration, but not much detail can be seen since this feature is viewed from the side. The crater lies across the southwestern rim of the much larger-walled plain Poczobutt.
Cooper is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the east of the large walled plain D'Alembert, and west-southwest of the crater Chappell.
Comrie is a lunar impact crater. It is located on the rugged far side of the Moon relative to the Earth, beyond the western limb. Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast.
Congreve is a lunar impact crater that is located on the far side of the Moon relative to the Earth, and lies across the lunar equator. It lies to the west-northwest of the massive walled plain Korolev. To the southeast is the crater Icarus, and due north is Zhukovskiy.
Ibn Firnas is a lunar impact crater on the far side of the Moon. In 1976 it was named after Abbas Ibn Firnas, a polymath from Andalucia who, in the 9th century, devised a chain of rings that could be used to simulate the motions of the planets and stars.
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.
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.
Stebbins is a large lunar impact crater on the far side of the Moon. It is located along the north-northeastern rim of the even larger crater Birkhoff, with about one-third of Stebbins laid across the interior of Birkhoff. To the north of Stebbins is the smaller Hippocrates, and to the west is Sommerfeld.
Roche is a large crater on the far side of the Moon from the Earth. The prominent crater Pauli lies across the southern rim of Roche, and the outer rampart of Pauli covers a portion of Roche's interior floor. To the north-northwest of Roche is the crater Eötvös, and just to the west-northwest lies Rosseland.
Wood is a lunar impact crater that lies entirely within the interior of the much larger walled plain Landau, on the far side of Moon. Wood is situated along the northwestern part of the floor of Landau, and shares a common northwestern rim with the larger impact. The inner wall of the northwest rim extends inward about halfway toward the crater midpoint, where there is a central peak. The rim of Wood is somewhat worn and uneven, with a small crater laid across the southwest section. The surviving interior floor is nearly level and is marked only by a few tiny craterlets.
Razumov is an impact crater on the far side of the Moon, beyond the northwestern limb as seen from the Earth. It lies along the southeastern outer rim of the walled plain Landau. Intruding slightly into the southern rim is the slightly smaller crater Petropavlovskiy. To the west-southwest lies Frost.
Smoluchowski is a lunar impact crater on the far side of the Moon. It lies in the part of the lunar surface that is sometimes brought into view of the Earth during periods of favorable libration and illumination from sunlight, but at such times little detail can be seen as the crater is observed from the edge. Smoluchowski lies across the northern rim of the larger walled plain Poczobutt. Nearly attached to the north-northeastern outer rim of Smoluchowski is the smaller crater Paneth.
Plummer is a lunar impact crater. It is located on the far side of the Moon from the Earth, to the north of the huge walled plain Apollo. Less than one crater diameter to the north of Plummer is the similar-sized Wilsing.
Siedentopf is a worn impact crater on the far side of the Moon. It lies to the east-southeast of the larger crater Vernadskiy. Farther to the south is Hoffmeister.
