Froelich is a lunar impact crater on the far side of the Moon. It is located in the northern regions, just beyond the north-northwestern limb. Only a few kilometers separate this formation from the crater Lovelace to the north. Farther to the south is the crater Merrill, and to the southeast along the limb is the larger Brianchon.

This crater has a circular, symmetrical shape but the rim is worn and does not project very far above the surface. The inner walls are generally featureless, except for small craterlets along the eastern and southern sides. The interior floor has a low ridge in the northeastern quadrant and a small central rise.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Froelich.

Andersson (crater)

Andersson is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. It is located just beyond the southwestern limb of the visible Moon in a location that can be viewed from the side during a favorable libration. The nearest crater of note is Guthnick to the north-northeast.

Avicenna (crater) Lunar impact crater

Avicenna is a lunar impact crater that lies on the far side of the Moon, just beyond the western limb on the northern rim of the Lorentz basin. It is named after the Persian physician Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.

Backlund (crater)

Backlund is a worn lunar impact crater that lies on the far side of the Moon, beyond the eastern limb. It lies astride the southern rim of the walled plain Pasteur, to the west of the crater Hilbert. Further to the west-southwest is Sklodowska. The north and south ends of Backlund are more worn and eroded than the intervening stretches. The interior floor is relatively flat, with the usual accompaniment of tiny impact craters marking the surface.

Chamberlin (lunar crater) Lunar impact crater

Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.

Brianchon (crater) Lunar impact crater

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.

Lovelace is a lunar impact crater that is located on the far side of the Moon, just behind the northern limb. It lies to the south-southwest of the crater Hermite, and just to the north of the slightly smaller Froelich. To the east is Sylvester.

Bell (crater) Lunar impact crater

Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.

Berkner (crater)

Berkner is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It is attached to the east-southeast rim of the crater Parenago. Just to the south is the Robertson, and to the southeast is Helberg.

Blackett (crater) Lunar impact crater

Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.

Bunsen (crater)

Bunsen is a lunar impact crater that lies near the northwestern limb of the Moon. It is located to the west of the Oceanus Procellarum and the crater von Braun. To the southeast is the crater Lavoisier, and to the northeast lies Gerard. Northwest of Bunsen, on the far side of the Moon, is McLaughlin. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.

Butlerov (crater)

Butlerov is a lunar impact crater that is located on the far side of the Moon, beyond the western limb and past the area sometimes brought into view through libration. It is located one crater diameter to the west of the crater Pease. Further to the west is the larger Kolhörster.

Bjerknes (lunar crater)

Bjerknes is a lunar impact crater that is located in the southern hemisphere on the rugged far side of the Moon. The crater lies behind the southeastern limb, and beyond the region that is sometimes brought into sight through libration. Thus this crater can not be viewed from Earth, and has only been seen from orbit. Nearby named craters are Clark to the east, and Pogson to the south-southwest.

De Roy (crater) Lunar impact crater

De Roy is a lunar impact crater that is located on the far side of the Moon, just behind the southwestern limb. This portion of the lunar surface is brought into view during favorable librations, allowing observation of this formation. However the crater is viewed from the side when watched from the Earth, and little detail can be seen. De Roy lies to the west of the crater Arrhenius, and east of the larger Boltzmann.

Cassegrain (crater) Lunar impact crater

Cassegrain is a lunar impact crater that is located on the far side of the Moon, beyond the southeastern limb. It lies to the southeast of the larger crater Lebedev, and to the northeast of the comparably-sized Priestley.

Cannizzaro (crater)

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.

Chadwick (crater)

Chadwick is a lunar impact crater that lies on the far side of the Moon's surface, just beyond the southwestern limb. It is located to the northwest of the crater De Roy, and was previously designated De Roy X before being given its current name by the IAU. This region of the lunar surface lies at the southern end of the ejecta blanket that surrounds the Mare Orientale impact basin.

Coulomb (crater) Lunar impact crater

Coulomb is a lunar impact crater that lies behind the northwestern limb, on the far side of the Moon. It is located to the west-southwest of the large crater Poczobutt, and northeast of Sarton.

Comrie (crater) Lunar impact crater

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.

Debus (crater)

Debus is a small lunar impact crater that is located on the far side of the Moon, past the eastern limb. It lies to the east-southeast of the crater Ganskiy, and just to the west of the huge walled plain Pasteur.

Lenard (crater)

Lenard is a lunar impact crater located on the lunar far side near the northern pole. The crater forms some of the wall of the crater Hermite, and is located North of the craters Lovelace and Froelich. Lenard was named after German physicist Philipp Lenard by the IAU, formally adopted as such in 2008. In 2020, upon learning of Lenard's support for the Nazi Party, Charles Wood, the chair of the Task Group for Lunar Nomenclature at the IAU, recommended to the IAU that the name "Lenard" be replaced.
