Eponym John Herschel

J. Herschel is a large lunar impact crater of the variety termed a walled plain crater. The crater is named after British astronomer John Herschel. [1] It is located in the northern part of the Moon's surface, and so appears foreshortened when viewed from the Earth. The southeastern rim of J. Herschel forms part of the edge of the Mare Frigoris lunar mare. To the northwest is the crater Anaximander. Bordering the northern rim is a large, unnamed lunar plain. Just to the south is the small crater Horrebow.

Contents

The rim of this crater has been heavily eroded, to the point where it is frequently described as "considerably disintegrated". The remaining rim survives as a ring of ridges that have been resculpted by subsequent impacts. The interior floor is relatively level, but irregular and marked by a multitude of tiny impacts. The most notable of these are the satellite craters C, D, K, and L, listed in the table below. Horrebow A is attached to the southern rim of the crater, and is overlapped along its southwest rim by Horrebow.

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 J. Herschel.

Eddington is the lava-flooded remnant of a lunar impact crater, located on the western part of Oceanus Procellarum. The western rim is attached to the wall of the walled plain Struve. To the east-southeast is the smaller but prominent crater Seleucus. South of Eddington is Krafft.

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

Finsch is a relatively small lunar impact crater in the mid-part of Mare Serenitatis that has been almost completely covered by the mare, forming a ghost crater in the lava plain. It was named after German zoologist Otto Finsch. It is located to the south-southeast of the crater Sarabhai and northeast of Bessel.

<span class="mw-page-title-main">C. Herschel (crater)</span> Lunar crater

C. Herschel is a small lunar impact crater that lies on the western part of Mare Imbrium. It is named after German astronomer Caroline Herschel. It is a circular, bowl-shaped formation that has not undergone significant erosion. The interior floor has the same low albedo as the surrounding lunar mare. To the south-southwest is the similar crater Heis. C. Herschel lies on a wrinkle ridge of the lunar mare named the Dorsum Heim.

Aristillus is a prominent lunar impact crater that lies in the eastern Mare Imbrium. It was named after Greek astronomer Aristyllus. Directly to the south is the smaller crater Autolycus, while to the southwest is the large Archimedes. To the northeast are the craters Theaetetus and Cassini.

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

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

Belʹkovich is a large lunar impact crater of the form termed a walled plain. The formation has been heavily eroded by a history of subsequent impacts, leaving it reshaped, worn, and the features softened and rounded. Belʹkovich is located along the northeastern limb of the Moon, and so its visibility is subject to libration effects. From the Earth this crater is viewed from the side, making it difficult to view it in detail.

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

De La Rue is the remnant of a lunar impact crater, or possibly several merged craters, creating a formation sometimes called a walled plain. It lies in the northeastern part of the Moon on the near side, and so appears foreshortened due to its location. This formation lies to the north-northwest of the prominent crater Endymion, just beyond the eastern extreme of Mare Frigoris. The crater Strabo intrudes into the northern part of De La Rue's northern rim, and the smaller Thales is attached to the northwestern part of the wall.

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

South is a large lunar impact crater that is located in the northwest part of the Moon. Most of the southern wall of this crater is joined to the Sinus Roris bay of the Oceanus Procellarum, with the southeast rim facing Mare Frigoris. Attached to the northwest of the formation is the larger walled plain Babbage. Just to the northeast is the crater Robinson, and farther to the northeast is another walled plain, J. Herschel.
