Struve is the lava-flooded remains of a lunar impact crater. It is located near the western extreme of the Oceanus Procellarum, close to the western lunar limb. As a consequence, even though it is roughly circular in outline, it appears oval due to foreshortening.
Schickard is a lunar impact crater of the form called a walled plain. It lies in the southwest sector of the Moon, near the lunar limb. As a result, the crater appears oblong due to foreshortening. Attached to the northern rim is the lesser crater Lehmann, and to the northeast is the even smaller Drebbel. Southwest of Schickard is Wargentin, a lava-flooded plateau.
Kies is the remnant of a lunar impact crater that has been flooded by basaltic lava, leaving only a remnant of the outer rim. It was named after German mathematician and astronomer Johann Kies. It is located in the Mare Nubium almost due south of the crater Bullialdus. Northwest of Kies is König. To the south-southwest lies a lunar dome structure designated Kies Pi (π). It has a small crater at the top and is most likely volcanic in origin.
Letronne is the lava-flooded remnant of a lunar impact crater. It was named after French archaeologist Jean-Antoine Letronne. The northern part of the rim is completely missing, and opens into the Oceanus Procellarum, forming a bay along the southwestern shore. The formation is located to the northwest of the large crater Gassendi.To the west-southwest is the flooded crater Billy, and north-northwest lies the smaller Flamsteed.
Hippalus is the remnant of a lunar impact crater on the eastern edge of Mare Humorum. It was named after ancient Greek explorer Hippalus. To the southeast is the crater Campanus, and to the northwest is the small flooded crater Loewy.
Meton is a compound formation on the Moon that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. It is located near the northern lunar limb, and is viewed from a low angle and foreshortened. The crater Barrow is attached to the southwest rim. To the northwest is the crater Scoresby, and to the east are Baillaud and Euctemon.
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.
Thomson is a lunar impact crater that is located within the Mare Ingenii on the far side of the Moon. Just to the northeast is the unusual merged crater formation of Van de Graaff. On the northwest rim of the mare is O'Day, and to the south-southwest is Obruchev on the southern shore of Mare Ingenii.
Parry is a lunar impact crater that is attached to the southeast rim of the walled plain Fra Mauro. It was named after British explorer William Parry. Attached to the west and southwest rim of Parry is the crater Bonpland. Due south of Parry is the small crater Tolansky, and farther to the south-southwest is Guericke.
Naonobu is a small lunar impact crater named after Japanese mathematician Ajima Naonobu. It is located on the eastern Mare Fecunditatis, to the northwest of the prominent crater Langrenus, and it forms a triple-crater formation with the adjacent Atwood to the south and Bilharz just to the southwest. Naonobu and Atwood are separated by only a few kilometres.
Joliot is a large lunar impact crater that lies on the far side of the Moon, just past the eastern limb. At this location it lies in a region of the surface that comes into sight during a favorable libration, although at such times it is viewed from the side. Thus viewing this crater in detail must be done from orbit.
Lassell is a small lunar impact crater that is located in the eastern part of the Mare Nubium. It was named after British astronomer William Lassell. It lies to the west of the crater Alpetragius and southwest of Alphonsus.
Baldet is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It lies in the lava-flooded region between the craters Cori to the north, Stoney to the southwest, and the worn walled plain Minkowski to the southeast.
Oppolzer is the remnant of a lunar impact crater that is located on the southern edge of Sinus Medii, along the meridian of the Moon. Its diameter is 41 km. It was named after the Austrian astronomer Theodor von Oppolzer. It is located within one crater diameter of the origin of the selenographic coordinate system at 0° N, 0° W. Attached to the surviving remnants of the southeast rim is the crater Réaumur. To the west-southwest is the lava-flooded walled plain Flammarion.
Gould is the remnant of a lunar impact crater formation that lies in the midst of the Mare Nubium, in the southwest quadrant of the Moon. It was named after American astronomer Benjamin A. Gould. It is located to the east-northeast of the prominent crater Bullialdus, and south of the crater remnant Opelt.
Opelt is the lava-flooded remnant of a lunar impact crater on the Mare Nubium. It lies to the north of a similar formation named Gould and to the northeast of the prominent Bullialdus.
Hall is a lunar impact crater in the southeast part of the Lacus Somniorum, a lunar mare in the northeast part of the Moon. It was named after American astronomer Asaph Hall. This feature can be found to the east of the prominent walled plain Posidonius. Just to the south, and nearly attached to the southern rim of Hall is the smaller crater G. Bond.
Pascal is a lunar impact crater that lies near the northern limb of the Moon, on the western side of the pole. It is located to the north of the eroded crater Desargues, and just east of Brianchon. Pascal can be located by finding the crater Carpenter and then following the surface to the northwest towards the limb. However the visibility of this formation can be affected by libration.
Mason is the remains of a lunar impact crater that lies in the northeastern part of the Moon. It is nearly attached to the eastern rim of the flooded crater Plana, and southeast of Bürg. Along the northern rim of Mason is the southern edge of the Lacus Mortis, a small lunar mare. To the south is the larger Lacus Somniorum.
Palmieri is a lunar impact crater that lies to the southwest of the Mare Humorum, in the southwestern quadrant of the Moon's near side. It lies due south of the crater Liebig and east-northeast of the larger Fourier.
