Eponym | Dmitry Dubyago and Alexander Dubyago |
Dubyago is a lunar impact crater that lies in the eastern limb of the Moon. It was named after Russian astronomers Dmitry Dubyago and Alexander Dubyago. [1] It appears significantly foreshortened when viewed from the Earth. It lies along the southern shore of the Mare Undarum, to the southeast of the crater Firmicus.
This crater has a somewhat worn outer rim which dips down to a low point along the northern rim, and has its maximum altitude along the eastern side. The most notable aspect of this crater, however, is the dark hue of the interior floor which matches the albedo of the lunar mare to the northwest. This darker shading makes the crater stand out somewhat from its surroundings.
Dubyago has an unusual number of satellite craters, several of which have since been given names by the IAU. The most notable of these is Dubyago B, which is nearly attached to the southeastern rim of the main crater.
The name of this crater has also been spelled Dubiago in some publications.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Dubyago.

The following craters have been renamed by the IAU:
Dawes is a lunar impact crater located in the wide straight between Mare Serenitatis and Mare Tranquilitatis. To its southwest lies the larger crater Plinius, and to its northeast sits the Mons Argaeus mountain rise. It is named after British astronomer William Rutter Dawes.
Boethius is a small lunar impact crater located on the east edge of Mare Undarum near the eastern lunar limb. To the southwest is the dark, lava-flooded crater Dubyago.
Censorinus is a tiny lunar impact crater located on a rise to the southeast of the Mare Tranquillitatis. It is named after the ancient Roman writer Censorinus. To the northeast is the crater Maskelyne.
Endymion is a lunar impact crater that lies near the northeast limb of the Moon. It is located to the east of Mare Frigoris, and north of the Lacus Temporis. To the southwest is the somewhat smaller crater Atlas. Because of its location, Endymion has an oval appearance from foreshortening. Beyond the crater along the lunar limb is the Mare Humboldtianum.
Bohnenberger is a lunar impact crater that lies near the east edge of the Mare Nectaris, in the foothills of the Montes Pyrenaeus mountain range that forms the perimeter of the mare. To the east beyond the mountains is the larger crater Colombo. The crater has a low rim along the north wall, and the floor is somewhat irregular with a ridge crossing the floor. There is a small crater along the western inner wall.
Liouville is a small lunar impact crater that is located near the eastern limb of the Moon. It was named after French mathematician Joseph Liouville. It lies to the southeast of the larger crater Dubyago, and was previously designated Dubyago S before being given a name by the IAU.
Condorcet is a lunar impact crater that is located in the eastern part of the Moon's near side, to the southeast of the Mare Crisium. It was named after French mathematician Marquis de Condorcet. To the northeast of Condorcet are the craters Hansen and Alhazen.
Stewart is a small lunar impact crater that lies to the northeast of the Mare Spumans, a small lunar mare near the eastern limb of the Moon. It was named after American astrophysicist John Quincy Stewart. It is located to the north of the crater Pomortsev, and to the southwest of the lava-flooded Dubyago. Stewart was previously designated Dubyago Q before being named by the IAU. This is a circular crater with a low outer rim and a level, featureless interior floor.
C. Mayer is a lunar impact crater that is located at the northern edge of the Mare Frigoris, due north of the prominent crater Aristoteles. Also to the south, but only a third as distant, is the smaller crater Sheepshanks. Due east of C. Mayer is the flooded crater Kane.
Pomortsev is a small lunar impact crater that is located in the eastern part of the Moon's near side. It was named after Russian rocketry scientist Mikhail Pomortsev. It lies on the eastern edge of Mare Spumans, to the southwest of the crater Dubyago. This formation was previously designated Dubyago P. One crater diameter to the north is the smaller Stewart.
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.
Gilbert is a large lunar impact crater that lies near the eastern limb of the Moon. Due to its location this feature appears foreshortened when viewed from the Earth, limiting the amount of detail that can be observed. The crater lies to the northwest of the similar-sized walled plain Kästner, to the west of the Mare Smythii.
Cook is a lunar impact crater that lies in the western part of the Mare Fecunditatis, just to the southeast of the prominent crater Colombo. To the southwest is Monge.
Macrobius is a prominent lunar impact crater located to the northwest of the Mare Crisium. Its diameter is 63 km. It was named after ancient Roman writer Macrobius. It lies on the southeast edge of the Lacus Bonitatis, a small lunar mare. The somewhat smaller crater Tisserand lies just to the east.
Chrétien is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the midpoint between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.
Leibnitz is a huge lunar impact crater that is located in the southern hemisphere on the far side of the Moon. This formation is the same size as Clavius on the near side. It is located to the east-southeast of Mare Ingenii, and is joined to the northeast rim of Von Kármán. Attached to the eastern rim of Leibnitz is Davisson, and intruding into the southeast rim is Finsen. Farther to the west is the large Oppenheimer.
Bliss is small lunar impact crater that is located just to the west of the dark-floored crater Plato. It lies in a region of continental terrain between Mare Imbrium to the south and Mare Frigoris to the north. This crater is bowl-shaped, with a small interior floor at the midpoint and a somewhat eroded outer rim.
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.
Magelhaens is a lunar impact crater that lies along the southwestern edge of the Mare Fecunditatis, in the eastern part of the Moon's near side. It was named after 16th-century Portuguese explorer Ferdinand Magellan. It lies to the south-southwest of the crater Goclenius, about midway between Gutenberg to the northwest and Colombo to the southeast.
Neujmin is a lunar impact crater on the Moon's far side. It is nearly attached to the west-southwest of the smaller crater Waterman, and lies to the southwest of the prominent Tsiolkovskiy.
