Jenner is a lunar crater that is located within the Mare Australe. It lies just past the southeastern limb, on the far side of the Moon, and can be viewed from the Earth during periods of favorable libration and lighting. Nearly attached to the eastern outer rim of Jenner is the larger, flooded crater Lamb.

Contents

This is a nearly circular crater with a sharp but somewhat irregular edge that has not been significantly eroded. There are some terraces, particularly along the southwestern inner walls, and some slumping along the southeastern rim. The interior floor has been flooded by basaltic lava, leaving a dark, level interior. There are no breaks in the exterior rim where the lava could have entered the crater, so it was presumably flooded from below. The floor is marked only by a few tiny craterlets. Surrounding Jenner is a rampart of ejecta that extends for over a half crater diameter in some directions.

Jenner is a crater of Upper (Late) Imbrian age. [1]

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

Archytas is a lunar impact crater that protrudes into the northern edge of Mare Frigoris.

Further to the southwest, beyond the opposite edge of the mare, is the dark-floored crater Plato.

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

Goddard is a lunar impact crater that is located along the eastern limb of the Moon, and so is visible from the edge from Earth. It is best viewed during favorable librations when the orientation of the Moon brings it further into sight. The crater is located in the Mare Marginis, to the northeast of the prominent crater Neper. Ibn Yunus, a crater remnant, is attached to the southeastern rim and is partly overlaid by Goddard. To the northeast is Al-Biruni.

<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.

Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.
