Eponym | Karl F. Sundman |
Sundman is a lunar impact crater that lies just past the western limb of the Moon. Although it lies on the far side from the Earth, this part of the surface is brought into view during periods of favorable libration and illumination. Sundman lies to the southwest of the walled plain Einstein, and to the west of the Vallis Bohr cleft. It was named after Finnish mathematician and astronomer Karl F. Sundman. [1]
This crater lies in the midst of the skirt of ejecta that surrounds the Mare Orientale impact basin. Both the crater and its surroundings have been modified by this enormous amount of material, and the surface displays an uneven pattern that is generally radial to the basin, which is located to the north. The crater forms a shallow depression in the surface, with small craters along the southeastern and southwestern rim.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Sundman.

The Lunar Atmosphere and Dust Environment Explorer (LADEE) mission ended with a planned lunar impact on April 18, 2014. Later, the exact impact location was found to be near the eastern rim of Sundman V crater. [2]
Anderson is a lunar impact crater that is located on the far side of the Moon. It is located to the northwest of the crater Sharonov, and the satellite crater Sharanov X is attached to the southeast rim of Anderson. To the northeast is the peculiar formation Buys-Ballot, and to the east-southeast lies the larger crater Spencer Jones.
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.
Landau is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It was named after physicist Lev Landau. The crater Wegener is attached to the northeastern rim. Attached to the southeastern rim is Frost.
Abel is an ancient lunar impact crater that lies near the southeast limb of the Moon's near side. It is located to the south of the crater Barnard, at the northwest edge of the Mare Australe.
Asclepi is a heavily eroded lunar impact crater that lies in the rugged southern highlands of the Moon. The outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result, the crater is now little more than a depression in the surface. The interior is nearly flat and relatively featureless.
Auwers is a small lunar impact crater located in the Montes Haemus mountain range at the south edge of Mare Serenitatis. It is named after German astronomer Arthur Auwers. It lies southeast of the crater Menelaus. The irregular rim of Auwers has a gap at the north-northwest edge, which allowed lava flows to reach the crater floor and flood the interior.
Doerfel is a lunar impact crater that is located in the vicinity of the southern pole, just on the far side of the Moon. It lies approximately midway between the large crater Hausen to the east-northeast and the even larger Zeeman to the southwest.
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.
Rost is a lunar impact crater that is located in the southwestern part of the Moon, to the southeast of the elongated formation Schiller. To the southeast of Rost is the larger crater Scheiner. West-southwest of this formation is the smaller Weigel.
Ellison is a lunar impact crater that lies on the far side of the Moon from the Earth. It is located just beyond the northwest limb of the Moon, to the southwest of the large walled plain Poczobutt. Due west of Ellison is the crater Coulomb.
Blanchard is a lunar impact crater that lies on the far side of the Moon, just behind the southwestern limb. It lies to the south-southwest of the crater Arrhenius, and northwest of Pilâtre. Further to the south is the rugged terrain to the north of the walled plain Hausen.
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.
Firmicus is a lunar impact crater that lies in the eastern part of the Moon's near side, so that from Earth it appears oval in shape due to foreshortening. It is, however, very nearly circular. The crater is located to the west of the Mare Undarum, and northeast of the similar-sized crater Apollonius. To the north of Firmicus are the craters van Albada and Auzout. Attached to its northwest rim is the Lacus Perseverantiae, a miniature lunar mare.
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.
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.
Chapman is a lunar impact crater that lies just beyond the northwest rim of the Moon, on the far side as seen from the Earth. It lies to the northeast of the crater Rynin, and southward of the large walled plain Poczobutt.
Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.
Dante is a lunar impact crater that is located on the far side of the Moon. It lies in the northern hemisphere exactly opposite the prime meridian facing the Earth. The nearest craters of note are Larmor to the north and Morse to the southeast. To the southwest is the oddly shaped Buys-Ballot.
Denning is a lunar impact crater that is located on the far side of the Moon. It lies about midway between the craters Levi-Civita to the south and Marconi to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin.
Rocca is a lunar impact crater that is located near the western limb of the Moon. It lies to the northwest of the flooded crater Crüger, and to the west of the Montes Cordillera. Just to the east-southeast of Rocca is the small Lacus Aestatis, a small lunar mare.
