Blazhko is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the northwest of the crater Joule, and to the south of Gadomski. The fresh, bright crater Wargo is to the south.

The rim of this crater is generally circular, but with some irregularities. There is a small outward bulge in the rim to the east-southeast, and an inward bulge on the opposite face. There is also a slight outward bulge along the north rim. The satellite crater Blazhko F is attached to the exterior of the east rim. The inner wall along the northeast face is striated with terraces. The interior floor is relatively level.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Blazkho.

Almanon (crater)

Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.

Arrhenius (lunar crater)

Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.

Baily (crater)

Baily is the remnant of a lunar impact crater on the boundary between Mare Frigoris to the north and Lacus Mortis to the south. The crater interior has been flooded by lava in the past, and only the northern half of the crater rim remains relatively intact. There is an outward bulge in the northeastern rim, possibly the remnant of another crater formation that once overlapped Baily. The crater interior is flat and relatively featureless, with no impacts of significance. The surviving outer rim reaches a maximum elevation of about 0.5 km.

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.

Cepheus (crater)

Cepheus is a lunar impact crater that is located in the northeastern part of the Moon, within one crater diameter of the larger crater Franklin to the southeast. To the north-north-east is the flooded crater Oersted. The proximity of this formation to the lunar limb means it appears oblong when viewed from the Earth due to foreshortening.

Ellison (crater)

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.

Baldet (lunar crater)

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.

Brunner (crater)

Brunner is a lunar impact crater that is located along the eastern limb of the Moon, to the southeast of the Mare Smythii. At this location the crater is viewed from the edge, and so it is not possible to see much detail from the Earth. The visibility of this formation is also affected by libration. The crater lies to the southwest of the walled plain Hirayama, and to the east of the elongated crater Houtermans.

Butlerov (crater)

Butlerov is a lunar impact crater that is located on the far side of the Moon, beyond the western limb and past the area sometimes brought into view through libration. It is located one crater diameter to the west of the crater Pease. Further to the west is the larger Kolhörster.

Campanus (crater)

Campanus is a lunar impact crater that is located on the southwestern edge of Mare Nubium. It was named after Italian astronomer Campanus of Novara. It forms a crater pair with Mercator just to the southeast. Along the southern rampart of Campanus is the small lunar mare named Palus Epidemiarum. To the southwest is the small crater Dunthorne.

Bronk (crater)

Bronk is an eroded crater that lies on the far side of the Moon, out of sight from the Earth. It lies to the southeast of the larger crater Kovalevskaya. Less than one crater diameter to the east-northeast is the smaller crater Bobone.

Elger (crater)

Elger is a lunar impact crater that lies along the southern edge of Palus Epidemiarum, the Marsh of Epidemics, in the southwest part of the Moon's near side. To the northeast is the flooded crater Capuanus, and farther to the northwest is Ramsden.

Carnot (crater)

Carnot is a large crater in the northern part of the Moon's far side. It intrudes into the southern rim of the huge walled plain Birkhoff. To the west-southwest of Carnot is the crater Paraskevopoulos.

Chadwick (crater)

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.

Foucault (crater)

Foucault is a small lunar impact crater that lies along the southern edge of Mare Frigoris, to the southeast of the crater Harpalus. In the rugged terrain to the south of Foucault is Sharp. The outer perimeter of Foucault forms a somewhat irregular circle, with slight outward bulges to the south and northeast. The inner wall of the rim is not notably terraced, and slopes down directly to the uneven floor. It is named after physicist Léon Foucault, most famous for the Foucault pendulum.

Drebbel (crater)

Drebbel is a small lunar impact crater named after Cornelius Drebbel that is located to the northeast of the large walled plain Schickard, in the southwestern part of the Moon. Further to the northeast is the Lacus Excellentiae and the small crater Clausius.

Eichstadt (crater)

Eichstadt is a lunar impact crater that is located in the eastern section of the Montes Cordillera range that encircles the Mare Orientale impact basin. It lies toward the southwestern limb of the Moon, and so appears oblong when viewed from the Earth due to foreshortening. Over 200 kilometers to the east of Eichstadt are the craters Darwin and Lamarck, and to the south is Krasnov.

Fontana is a lunar impact crater that is located in the southwestern part of the Moon's near side, to the south of the Oceanus Procellarum. It lies to the west-northwest of the flooded crater Zupus. Midway between Fontana and Zupus is a rille system designated Rimae Zupus.

Henry (lunar crater)

Henry is a lunar impact crater that is located to the northwest of the larger crater Cavendish, in the southeastern part of the Moon's near side. It was named after the Scottish-American scientist Joseph Henry. Less than a half diameter to the northwest is similar-sized crater Henry Frères, named for the brothers Paul and Prosper Henry.

Lane (crater)

Lane is a lunar impact crater. It lies on the far side of the Moon, just to the west of the crater Ten Bruggencate. It was named after American astrophysicist Jonathan H. Lane. To the west of Lane is Perepelkin, and to the northwest lies Love.
