Eponym John S. Plaskett

Plaskett is a prominent lunar impact crater that is located on the northern hemisphere on the far side of the Moon. It lies only a few hundred kilometers south of the lunar north pole, and the sunlight it receives is at a low angle. The large walled plain Rozhdestvenskiy is attached to the northeast rim of Plaskett, between the crater and the pole. To the south is the overlapping crater pair of Milankovic and Ricco.

Contents

The outer rim of Plaskett has a somewhat polygonal shape formed from outward bulges in the perimeter. The inner wall is terraced along the southern edge, while the remainder is rougher and less finely featured. The interior floor is relatively flat and there is a central peak formed of a double-mount at the midpoint. The satellite crater Plaskett U is attached to the northwest rim.

Because of the isolation of this crater and its location near the lunar limb, it has been suggested as the ideal spot for a future lunar base. A base here would allow simulation of a mission to Mars. [1]

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 Plaskett.

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

Amundsen is a large lunar impact crater located near the south pole of the Moon, named after the Norwegian explorer Roald Amundsen. It lies along the southern lunar limb, and so is viewed from the side by an observer on the Earth. To the northwest is the crater Scott, a formation of similar dimensions that is named for another Antarctic explorer. Nobile is attached to the western rim.

Holden (lunar crater) Feature on the moon

Holden is a lunar impact crater attached to the southeast rim of the much larger crater Vendelinus. The crater rim is impacted by a craterlet on the north-northwest, and it possesses a terrace along the northeast interior wall. The floor of the crater is flat with no central peak. There is a small crater on the floor just to the south of the midpoint. It is named after Edward Singleton Holden. A crater with the same name exists on Mars.

<span class="mw-page-title-main">Byrd (lunar crater)</span> Feature 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.

Crommelin (lunar crater) Lunar impact crater

Crommelin is an ancient lunar impact crater that is located in the vicinity of the south pole of the Moon, on the far side. It lies to the north of the large crater Zeeman, and to the east-northeast of Numerov.

Doerfel (crater) Lunar impact crater

Doerfel is a lunar impact crater that is located in the vicinity of the southern pole, just on the far side of the Moon. It lies approximately midway between the large crater Hausen to the east-northeast and the even larger Zeeman to the southwest.

Gioja (crater) Feature on the moon

Gioia is a lunar impact crater that is located in the vicinity of the north pole of the Moon. It is named after the Italian inventor Flavio Gioia. As it lies so close to the northern limb, it is viewed nearly from the edge making difficult to observe from the Earth. The crater is attached to the southern rim of the larger Byrd, a formation with low walls. To the south-southeast is the crater Main.

<span class="mw-page-title-main">Rozhdestvenskiy (crater)</span> Feature on the moon

Rozhdestvenskiy is a large lunar impact crater that is located on the far side of the Moon, within one crater diameter of the north pole. It lies sandwiched between the craters Hermite along the eastern rim, and Plaskett which intrudes slightly into the west-southwestern rim. Just on the opposite side of the pole is the crater Peary.

Sylvester (crater) Lunar impact crater

Sylvester is a lunar impact crater that is located near the north pole of the Moon, along the northern limb in the libration zone. It lies just to the south-southeast of the craters Grignard and Hermite; the latter of which is within one crater diameter of the pole. South of Sylvester is Pascal. Due to its location, Sylvester receives sunlight at only a low angle.

Fontenelle (crater) Feature on the moon

Fontenelle is a lunar impact crater that is located along the northern edge of Mare Frigoris, in the northern part of the Moon. To the northeast is the remnant of the crater Birmingham. Due to its location, this crater appears oval in shape when observed from the Earth because of foreshortening.

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

Berlage is an old lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The smaller crater Bellinsgauzen is attached to its northern rim, and Cabannes is less than one crater diameter to the northwest. To the east-northeast of Berlage is Lemaître.

C. Mayer (crater) Impact crater

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.

De Forest (crater) Lunar impact crater

De Forest is a lunar impact crater on the far side of the Moon. It is located in the far southern hemisphere, to the west of the large walled plain Zeeman and due south of the crater Numerov. Because of its proximity to the southern pole, this crater receives sunlight at an oblique angle when it is on the illuminated half of the Moon.

Cajori (crater) Feature on the moon

Cajori is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It lies to the southwest of the walled plain Von Kármán, and to the east-southeast of the crater Chrétien.

Chapman (crater) Feature on the moon

Chapman is a lunar impact crater that lies just beyond the northwest rim of the Moon, on the far side as seen from the Earth. It lies to the northeast of the crater Rynin, and southward of the large walled plain Poczobutt.

Delporte (crater) Feature on the moon

Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim. The crater is named after Eugène Joseph Delporte.

Denning (lunar crater) Lunar impact crater

Denning is a lunar impact crater that is located on the far side of the Moon. It lies about midway between the craters Levi-Civita to the south and Marconi to the north-northeast. About two crater diameters to the southeast is the huge walled plain Gagarin.

Donner (crater) Lunar impact crater

Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.

Finsen (crater) Feature on the moon

Finsen is a lunar impact crater that is located in the southern hemisphere, on the Moon's far side. It is attached to the southeastern exterior of the walled plain Leibnitz, and the ejecta from Finsen covers the southeastern part of Leibnitz's interior floor. To the southwest of Finsen is another walled plain, Von Kármán, partly overlain by Leibnitz.
