Zeno is a lunar impact crater located near the northwestern limb of the Moon. It lies to the east-southeast of the crater Mercurius. Farther to the east of Zeno, along the limb, is the well-formed crater Boss.
The rim of Zeno is slightly distorted and has received some erosion due to subsequent impacts. There is a depression in the surface attached to the eastern rim, forming a bulging extension. Small craters lie on the southern rim and across the interior of the northern wall. The crater Zeno B is attached to the exterior of the southwestern rim, and the distorted Zeno A is attached in turn to the western rim of Zeno B.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zeno.

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.
Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
Chacornac is an irregular lunar impact crater attached to the southeast rim of the crater Posidonius. It lies just to the east of the Mare Serenitatis, and north of the crater Le Monnier. The crater is named after French astronomer Jean Chacornac.
Zsigmondy is a lunar impact crater located beyond the northwestern limb on the far side of the Moon. Attached to the southeastern rim of the crater is the crater Omar Khayyam, which lies within the much larger Poczobutt. Farther to the east, along the north rim of Poczobutt, is Smoluchowski.
Abel is an ancient lunar impact crater that lies near the southeast limb of the Moon's near side. It is located to the south of the crater Barnard, at the northwest edge of the Mare Australe.
Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.
Babbage is an ancient lunar impact crater that is located near the northwest limb of the Moon, named after Charles Babbage. It is attached to the southeastern rim of the prominent crater Pythagoras. The crater remnant named South intrudes into the southeastern floor of Babbage.
Barnard is a lunar impact crater that is located near the eastern limb of the Moon. It is attached to the southeast rim of the large crater Humboldt, and Abel lies directly to the south. To the northeast is the crater Curie, while to the southeast is the Mare Australe.
Bohr is a lunar impact crater that is located near the western lunar limb, in the area that is affected by librations. It is attached to the southwestern rim of the larger, eroded Vasco da Gama formation, and to the southeast of the crater Einstein. The crater was observed for the first time in 1963, by Arthus and Ewen Whitaker in the book Rectified Lunar Atlas.
Boole is a lunar impact crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has been worn and rounded due to subsequent impacts. It is named after George Boole.
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.
Berkner is a lunar impact crater that is located on the far side of the Moon, just past the western limb. It is attached to the east-southeast rim of the crater Parenago. Just to the south is the Robertson, and to the southeast is Helberg.
Liouville is a small lunar impact crater that is located near the eastern limb of the Moon. It was named after French mathematician Joseph Liouville. It lies to the southeast of the larger crater Dubyago, and was previously designated Dubyago S before being given a name by the IAU.
Helmholtz is a lunar impact crater, approximately 110 kilometers in diameter, that is located near the south-southeast limb of the Moon. Attached to the south-southeast rim of Helmholtz is the somewhat smaller crater Neumayer. The larger crater Boussingault is nearly attached to the west-southwestern rim.
Lavoisier is a lunar impact crater that is located near the northwestern limb of the Moon, at the western edge of the Oceanus Procellarum. It is named after the French chemist Antoine Lavoisier. It is located to the southwest of the crater von Braun and southeast of Bunsen. Due south of Lavoisier is the disintegrated crater Ulugh Beigh.
Seneca is a lunar impact crater that is located towards the east-northeastern limb, less than one crater diameter to the north of Plutarch. To the northwest is the crater Hahn, and due north lies the large walled plain Gauss.
Lebesgue is a small lunar impact crater that is located near the eastern limb of the Moon. It lies in the southeastern part of the Mare Smythii, to the southeast of the crater Warner. The southeastern rim of Lebesgue is attached to a small crater that overlays the northwest rim of Swasey, so that the three form a short crater chain. This is a circular, bowl-shaped crater formation. It is not notably eroded or overlain by impacts.
von Braun, named after the rocket pioneer Wernher von Braun, is a lunar impact crater located near the northwestern limb of the Moon. It lies along the western edge of the Oceanus Procellarum, to the northeast of the crater Lavoisier. The northeastern rim of this crater is on the edge of the Sinus Roris, a bay feature in the northwestern part of the Oceanus Procellarum. Due to its proximity to the limb, this crater appears significantly foreshortened when viewed from the Earth.
Edison is a lunar impact crater on the far side of the Moon. It is located just behind the north-northeastern limb of the Moon, a region that is sometimes brought into sight from Earth during favorable librations. However even at such times not much detail can be discerned, and the crater is better observed by orbiting spacecraft.
Stefan is a lunar impact crater on the far side of the Moon, just beyond the northwestern limb. Attached to the western rim is the slightly smaller crater Wegener, and close to the eastern rim is Rynin.
