Guillaume is an old lunar impact crater on the Moon's northern hemisphere, and is located on the far side relative to the Earth. It lies just to the southeast of the slightly larger crater Perkin. This is a worn and eroded formation, with features that have been softened and rounded over time. A cluster of small craters covers most of the northeastern rim. Several small craterlets lie along the edge to the south and west. The bowl-like interior is nearly featureless, with only a few small craterlets to mark the surface.

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 Guillaume.

Agatharchides (crater)

Agatharchides is a lunar impact crater located at the southern edge of Oceanus Procellarum, in the region between the Mare Humorum and Mare Nubium. To the east-southeast is the crater Bullialdus, and to the south-southwest lies Loewy. It is named after the Greek geographer Agatharchides.

Appleton (crater)

Appleton is a heavily eroded lunar impact crater that lies in the northern hemisphere on the far side of the Moon. To the northwest are the craters Von Neumann and Campbel. The smaller Golovin lies to the northeast, while further to the southwest is the Mare Moscoviense.

Armiński (crater)

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.

Bergstrand (crater)

Bergstrand is a lunar impact crater that lies on the far side of the Moon. It is located just to the southeast of the prominent crater Aitken, and northeast of the walled plain Vertregt.

Bose (crater)

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 (crater)

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 (crater)

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 (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.

Breislak (crater)

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.

Bredikhin (crater)

Bredikhin is a lunar impact crater that is located on the far side of the Moon. It lies just to the west of the crater Mitra, and northeast of Raimond.

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.

Comstock (crater)

Comstock is a lunar impact crater that is located on the far side of the Moon. It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.

Cockcroft (crater)

Cockcroft is a lunar impact crater that is situated on the far side of the Moon from the Earth, so that it has only be observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.

Congreve (crater)

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.

Fraunhofer (crater)

Fraunhofer is a lunar impact crater that is located just to the south-southwest of the walled plain Furnerius, in the southeastern part of the Moon. This crater appears foreshortened when viewed from the Earth, and is actually nearly circular.

Danjon (crater)

Danjon is a lunar impact crater on the far side of the Moon. It lies less than a crater diameter to the east-southeast of the larger crater Langemak. To the east-northeast of Danjon is the crater Perepelkin, and due south lies the walled plain Fermi.

Donner (crater)

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.

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.

Perkin (crater)

Perkin is a lunar impact crater that is located in the northern hemisphere on the Moon's far side. Immediately to the north is the larger crater Debye. Just to the southeast is the somewhat smaller cater Guillaume, and to the west-southwest lies Dunér. To the northwest of Perkin is the large walled plain D'Alembert.
