Ukert is a lunar

Moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

 impact crater

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

 that lies on a strip of rugged ground between Mare Vaporum

Mare Vaporum

Mare Vaporum is a lunar mare located between the southwest rim of Mare Serenitatis and the southeast rim of Mare Imbrium. The lunar material surrounding the mare is from the Lower Imbrian epoch, and the mare material is from the Eratosthenian epoch. The mare lies in an old basin or crater that is...

 to the north and Sinus Medii

Sinus Medii

Sinus Medii is a small lunar mare that is located at the intersection of the Moon's equator and prime meridian. As seen from the Earth, this feature is located in the central part of the Moon's near side, and it is the point closest to the Earth...

 in the south. It is located to the north-northwest of the crater Triesnecker

Triesnecker (crater)

Triesnecker is a prominent lunar impact crater that is located in the Sinus Medii, near the central part of the Moon's near side. It is located to the north-northwest of the crater Rhaeticus, and to the east-southeast of the flooded Murchison....

Pallas (crater)

Pallas is a heavily eroded lunar crater located to the north of the Sinus Medii. To the northwest is the smaller but less worn crater Bode. Pallas shares a low wall with the crater Murchison that is attached to the southeast, and there are two gaps in the shared rim.The outer wall of Pallas is...

 and Murchison

Murchison (crater)

Murchison is a lunar crater on the north edge of the Sinus Medii, named in honour of the geologist Sir Roderick Murchison. It shares a section of rim with the crater Pallas. To the southeast on the mare is the circular crater Chladni, and to the northeast is Ukert. Farther to the east is the...

.

The outer rim of this crater is not quite circular, with outward bulges to the north and the east. The interior floor is irregular in places, with a central ridge running from crater mid-point down to the southern wall. There is a tiny craterlet along the northern rim, but otherwise the crater contains no impacts of note.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Ukert.
