Dirichlet is a lunar impact crater that is located on the Moon's far side. It is attached to the southern outer rim of the crater Henyey. To the south-southeast is the much larger crater Tsander.
This is a circular crater with a sharp-edged rim that is not significantly worn. There are slight outward protrusions along the eastern side. The sides of the inner walls have slumped down to form a ring of scree along the base.
Dirichlet lies on the eastern margin of the Dirichlet-Jackson Basin.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Dirichlet.

Zhukovskiy is a lunar impact crater that lies on the far side of the Moon. It forms a pair with Lebedinskiy, which is attached to the eastern rim. There are no other named craters of note in the immediate vicinity, although the immense walled plain Korolev lies farther to the southeast.
Alekhin is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies to the north of the crater Zeeman, and south-southeast of Fizeau. To the west lies Crommelin, and east-southeast is Doerfel.
Alhazen is a lunar impact crater that lies near the eastern limb of the Moon's near side. Just to the south-southeast is the crater Hansen, and to the west is the Mare Crisium. The rim of Alhazen is nearly circular, but appears highly oblong when viewed from the Earth due to foreshortening. The inner walls and the crater floor are rugged and irregular. A low ridge joins the south rim of Alhazen with the nearby Hansen. The crater is named after the Arab Muslim scientist, Ibn al-Haytham.
Berlage is an old lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The smaller crater Bellinsgauzen is attached to its northern rim, and Cabannes is less than one crater diameter to the northwest. To the east-northeast of Berlage is Lemaître.
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.
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.
Chappell is a lunar impact crater that is located on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. This feature is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
Chevallier is a lunar impact crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh.
Coriolis is a lunar impact crater that is located on the far side of the Moon. The crater floor is bisected by the lunar equator, and it lies about three crater diameters northwest of the crater Daedalus.
Charlier is a lunar impact crater that is located on the far side of the Moon. To the south-southeast is the larger crater Kovalevskaya, and northeast of Charlier is Perrine.
Fourier is a lunar impact crater that is located in the southwestern part of the Moon's near side, just to the southeast of the crater Vieta. To the northeast is the Mare Humorum. The rim of this crater is roughly circular, but appears oval when viewed from the Earth due to foreshortening.
Dellinger is a lunar impact crater that is located on the Moon's far side. It is attached to the southern rim of the crater Pannekoek. To the southeast lies the crater Marconi, and to the southwest is Chauvenet.
Fleming is a large lunar impact crater that is located on the Moon's far side, and cannot be seen from the Earth. It lies about a crater diameter to the east-northeast of Hertz, and to the northwest of Lobachevskiy.
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.
Henyey is a lunar impact crater that lies on the far side of the Moon from the Earth. It is attached at the southern end to the northern rim of the crater Dirichlet. Less than a crater diameter to the northeast is the large crater Mach, and to the northwest lies Mitra.
Mach is a large lunar impact crater of the class known as a walled plain. It is located on the far side of the Moon and cannot be viewed directly from the Earth. Nearby craters of note include Joule to the northeast, Mitra attached to the western outer rim, and Henyey to the southwest.
Lebedinskiy is an impact crater on the far side of the Moon. It is attached to the eastern outer rim of the somewhat larger crater Zhukovskiy. About two crater diameters to the east-southeast lies the smaller Engel'gardt. The satellite crater Lebedinskiy P lies in the southern indentation of terrain between Lebedinskiy and Zhukovsky, and is nearly attached to the southwest rim of Lebedinskiy.
Mitra is a lunar impact crater that is attached to the western outer rim of the larger crater Mach, on the far side of the Moon. Just to the west of Mitra is Bredikhin, and to the south-southeast lies Henyey. It is named after Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan award recipient known for his pioneering work in the field of ionosphere and radiophysics.
McMath is an impact crater on the Moon's far side. It lies to the south-southwest of the prominent crater Jackson, and material from the ray system centered on Jackson lies across most of McMath. Farther to the south lies the crater pair of Zhukovskiy and Lebedinskiy.
Tsander is a large lunar impact crater on the far side of the Moon. Attached to the southeastern outer rim is the younger crater Kibal'chich. To the northwest lies Dirichlet, and to the northeast lies Artem'ev.
