Ukert is a lunar impact crater that lies on a strip of rugged ground between Mare Vaporum to the north and Sinus Medii in the south. It was named after German historian Friedrich August Ukert. [1] It is located to the north-northwest of the crater Triesnecker and northeast of the crater pair of Pallas and Murchison.

Contents

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 midpoint down to the southern wall. There is a tiny craterlet along the northern rim, but otherwise the crater contains no impacts of note.

Ukert is a crater of Lower (Early) Imbrian age. [2]

Satellite craters

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

Brayley is a lunar impact crater located in the southwest part of the Mare Imbrium. It was named after British geographer Edward W. Brayley in 1935. It has a circular rim and a low rise in the center. There are no notable craters overlapping the rim or interior. The sinuous rille Rima Brayley passes to the north of Brayley.

<span class="mw-page-title-main">Murchison (crater)</span> Crater on the Moon

Murchison is a lunar impact crater on the north edge of the Sinus Medii. It was 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 prominent Triesnecker. Murchison lies astride the lunar zenith line, i.e. the starting longitude of the selenographic coordinate system.

<span class="mw-page-title-main">Boss (crater)</span> Lunar impact crater

Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects. It was named by the IAU in 1964 for astronomer Lewis Boss.

<span class="mw-page-title-main">Byrd (lunar crater)</span> Crater on the Moon

Byrd is an irregular lunar impact crater that is located near the north pole of the Moon. The north rim of Byrd is nearly connected to the crater Peary, a formation that is adjacent to the pole. The smaller crater Gioja is attached to the remains of the southwest rim.

<span class="mw-page-title-main">Bragg (crater)</span> Crater on the Moon

Bragg is an ancient lunar impact crater that is located on the far side of the Moon, just beyond the northwest limb. This formation has been heavily eroded and reshaped by subsequent impacts, leaving an irregular depression in the surface. The most intact portion of the rim is along the western face, while the northern and eastern rim has been nearly worn away and is overlaid by several smaller craters. The most notable of these is Bragg H, which lies across the east-southeastern rim.

<span class="mw-page-title-main">Cepheus (crater)</span> Crater on the Moon

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.

<span class="mw-page-title-main">Bell (crater)</span> Lunar impact crater

Bell is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It lies in an area of terrain that is marked by many small craters, a number of which are satellite craters of Bell listed in the table below. Bell lies within two crater diameters of Laue to the north, and to the west of the smaller Helberg.

<span class="mw-page-title-main">Casatus (crater)</span> Lunar impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

<span class="mw-page-title-main">Demonax (crater)</span> Lunar impact crater

Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky.

Chappell is a lunar impact crater on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. It is in a heavily bombarded section of the surface, and much of its outer rim is overlain by smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
