Barbier is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It forms a matched pair with Cyrano to the north-northwest, and it lies to the southeast of the huge walled plain Gagarin. Southwest of Barbier is the crater Sierpinski, and to the southeast is the Mare Ingenii.

Contents

The outer rim of Barbier has been eroded somewhat by subsequent impacts, particularly at the north end where the wall has been degraded by several small craterlets. A small crater lies across the eastern rim, and the southern rim is wider and irregular in shape. An unusual irregular crater (Barbier F) with a hummocky floor, approximately 16 km long, lies near where a central peak would be located, offset to the east of the midpoint.

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 Barbier.

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

Dawson is a lunar impact crater that lies on the southern hemisphere on the far side of the Moon. It lies across a crater triplet: the southeast rim is intruding into the crater Alekhin; the northwest rim also intrudes into the larger satellite crater Dawson V, and the northeast rim is attached to the comparably sized Dawson D. To the south of this formation is the large crater Zeeman. West of Dawson is the crater Crommelin, and to the north lies Fizeau.

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

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.

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

Barringer is a lunar impact crater that is located on the southern hemisphere on the Far side of the Moon, named after geologist Daniel Barringer. It is attached to the north-northeastern rim of the walled basin named Apollo, and lies to the southeast of Plummer. South of Barringer, on the floor of the Apollo basin, is the crater Scobee.

Brouwer is a large lunar impact crater that is located in the southern hemisphere on the far side of the Moon. Intruding into the western rim of Brouwer is the younger and somewhat smaller crater Langmuir. Further to the east-southeast is the larger walled plain Blackett.

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

Campbell is a large lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It lies to the southwest of the walled plain D'Alembert, an even larger formation. If Campbell were located on the near side of the Moon as seen from the Earth, it would form one of the largest visible craters, being slightly larger than Schickard. It is bordered by several craters of note, with Wiener to the southwest, Von Neumann just to the south, Ley overlying the southeast rim, and Pawsey to the west.

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

De Sitter is a lunar impact crater that is located near the northern limb of the Moon, to the north of the Baillaud–Euctemon crater pair. Due to its location, this crater appears very foreshortened when viewed from the Earth, limiting the detail that can be viewed. The crater also receives sunlight at a low angle, when it is on the sunlit side.

Chappell is a lunar impact crater on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. It is in a heavily bombarded section of the surface, and much of its outer rim is overlain by smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.
