Wollaston is a relatively small lunar impact crater located in the Oceanus Procellarum. To the northwest is the similar Nielsen. To the southeast is the somewhat larger Krieger. There are several small rilles to the southwest of Wollaston, forming part of the Rimae Prinz.

The crater was formally named by the IAU in 1935. [1]

This is a circular, cup-shaped crater with a higher albedo than the surrounding mare. It has a raised rim that is free from impact erosion, and is surrounded by a small radial skirt of ejecta. The crater has not been significantly eroded by subsequent impacts.

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

Born is a small lunar impact crater located near the eastern edge of the Moon, to the northeast of the prominent crater Langrenus. It was previously designated Maclaurin Y before being named by the IAU in 1979. Maclaurin itself lies to the north.

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

Carrillo is a small lunar impact crater located near the eastern limb of the Moon. In this location the crater is subject to lunar libration effects, and appears highly oval due to foreshortening. It is located on the slope of highlands on the west side of Mare Smythii, and its inner wall is wider on the western side than to the east.

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

Nielsen is a lunar impact crater on the Oceanus Procellarum. It is located north-east of Montes Agricola on the western hemisphere of the Moon. To the east-southeast is the crater Wollaston.

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

Artamonov is a lunar impact crater on the far side of the Moon. Its eroded outer rim does not have the circular shape of most lunar craters, but the overall shape of three or four merged craters. The largest is in the south, with smaller circular bulges to the north and east.

<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">Back (crater)</span> Crater on the Moon

Back is a small lunar impact crater that is located near the eastern limb of the Moon. It lies on the northwest edge of the Mare Smythii, and the northeast rim is adjacent to the crater Schubert. To the west is Jenkins, and to the southwest is the Weierstrass–Van Vleck crater pair.

<span class="mw-page-title-main">Fechner (crater)</span> Lunar surface depression

Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northwards from the periphery of the northeast rim.

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

Krieger is a lunar impact crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent ray crater Aristarchus. To the northwest lies the small Wollaston. The crater was formally named in 1935.

de Gerlache (crater) Lunar impact crater

de Gerlache is a lunar impact crater that is located along the southern limb of the Moon, within a crater diameter of Shackleton at the south pole. From the Earth this crater is seen from the edge, and it lies in perpetual darkness. Thus little or no detail can be seen of this crater, other than the edge of the rim. However, the crater is clearly visible in Earth-based radar images. The crater is roughly circular, with some slight wear. No craters of note overlie the rim, although some formations may be attached to the southern and western edges.

Van Biesbroeck is a small lunar impact crater that interrupts the southern rim of the lava-flooded crater Krieger, in the Oceanus Procellarum. The crater is circular and symmetrical, with sloping inner walls that run down to a small interior floor. Van Biesbroeck was designated Krieger B before the IAU gave it a unique name in 1976.

Cori is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies less than one crater diameter to the north of the crater Baldet. To the northeast is the crater Grissom. It is named after Gerty Cori, the first American woman to win the Nobel Prize and the first woman to win the prize in the category Nobel Prize in Physiology or Medicine.

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

Chevallier is a lunar impact crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh. Chevallier was named by the IAU in 1935.

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

Carrington is a lunar impact crater that is located just to the northeast of the crater Schumacher, in the northeastern part of the near side of the Moon. Carrington was named by the IAU in 1935. It lies in a stretch of rough terrain between two small lunar maria, with Lacus Temporis to the northwest and the smaller Lacus Spei to the east. To the northeast of Carrington is Mercurius.

<span class="mw-page-title-main">Chappe (crater)</span> Lunar surface depression

Chappe is a lunar impact crater that lies along the southwestern limb of the Moon. It is nearly attached to the northern limb of the walled plain Hausen, and an equal distance from the crater Pilâtre. To the north-northwest is Blanchard.

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

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

Florensky is a lunar impact crater that is attached to the northeastern rim of the larger crater Vernadskiy. It is located on the far side of the Moon and cannot be directly seen from the Earth. The rim of this crater has been heavily eroded and it forms an irregular ring about the uneven interior. This crater was previously identified as Vernadskiy B before being assigned a name by the IAU in 1985.

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

Grigg is a lunar impact crater that is located on the far side of the Moon. It lies in the northern outskirts of the huge walled plain Hertzsprung, to the southwest of the crater Fersman and southeast of Poynting. The rim of this crater is generally circular, with a small impact crater intruding into the eastern edge. A small crater fills the northwestern part of the interior floor.
