Eponym Joseph Winlock

Winlock is a lunar impact crater on the far side of the Moon, where it lies to the west of the large walled plain Lorentz. From the Earth this crater is located behind the northwestern limb, and just beyond the parts of the far side that are sometimes brought into view due to libration.

This is a reasonably well-formed crater, although it has suffered some erosion. There is a small crater lying across the rim to the southwest, and a smaller crater across the northeastern rim. The rim edge is otherwise relatively circular with some slight slumping along the inner edge. The interior floor is generally level, and the site where a central peak is usually located is instead occupied by a small craterlet.

Prior to formal naming by the IAU in 1970, [1] Winlock was called Crater 174. [2] The crater Winlock M, to the south of Winlock, was called Crater 175.

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 Winlock.

Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.

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

Atwood is a small earth moon impact crater that is located on the Mare Fecunditatis, to the northwest of the prominent crater Langrenus. It forms a triple-crater formation with Naonobu attached to the north rim and Bilharz near the west rim.

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

Avicenna is a lunar impact crater that lies on the far side of the Moon, just beyond the western limb on the northern rim of the Lorentz basin. It is named after the Persian polymath Avicenna. It lies to the north-northwest of the larger crater Nernst, and to the southeast of Bragg.

<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">Fabry (crater)</span> Impact crater

Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.

<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.

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.
