Cannon is a lunar impact crater that is located near the east-northeastern limb of the Moon's near side. It lies just to the northwest of the Mare Marginis, and south-southeast of the crater Plutarch. Farther to the east-northeast is Hubble.

Contents

This is a worn and eroded formation with an interior floor that has been resurfaced by lava. A small crater overlies the north rim, which forms a notch in the side. Tiny craters also lie across the rim northeast and at the southern edge. The interior is level and nearly featureless, with only a few tiny scattered craterlets to mark the surface. This floor has the same albedo as the surrounding terrain.

The crater is named after Annie Jump Cannon, an astronomer who classified 300,000 stellar bodies.

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 Cannon.

Anaximenes (crater) Lunar impact crater

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.

Anderson (crater) Lunar impact crater

Anderson is a lunar impact crater that is located on the far side of the Moon. It is located to the northwest of the crater Sharonov, and the satellite crater Sharanov X is attached to the southeast rim of Anderson. To the northeast is the peculiar formation Buys-Ballot, and to the east-southeast lies the larger crater Spencer Jones.

Bartels (crater) Lunar impact crater

Bartels is a lunar impact crater located along the western perimeter of the Moon's visible face. At this location the crater is viewed from the side, and visibility is affected by libration. The crater can be viewed in its entirety only from lunar orbit. It is located to the north of the crater Moseley and south-southeast of Voskresenskiy.

Almanon (crater) Lunar crater of caliph Al-Mamun

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.

Fizeau (crater) Lunar impact crater

Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.

Becquerel (lunar crater) Lunar impact crater

Becquerel is a lunar impact crater that lies in the northern hemisphere on the far side of the Moon. This is an ancient and heavily worn formation that is now little more than an irregular buri in the surface. The outer rim has been worn and reshaped until it forms a rugged, mountainous region around the flatter interior.

Boltzmann (crater) Lunar impact crater

Boltzmann is an old lunar impact crater that is located along the southern limb of the Moon, in the vicinity of the south pole. At this location the crater is viewed from the side from Earth, and so not much detail can be seen. It is located to the north of the walled plain Drygalski, and to the west of the crater Le Gentil.

Berzelius (crater)

Berzelius is a lunar impact crater located in the northeast part of the Moon's near side. It lies to the southeast of the crater Franklin, and to the northwest of Geminus.

Casatus (crater) Lunar impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

Carver (crater) Lunar impact crater

Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.

De Moraes (crater) Lunar impact crater

De Moraes is a lunar impact crater that is located in the northern part of the Moon's far side. It lies to the northeast of the larger crater Bridgman, and southwest of van Rhijn.

Dyson (crater) Lunar impact crater

Dyson is a lunar impact crater, 63 kilometers in diameter, that lies on the far side of the Moon, past the northwest limb. It is located in the northern part of the surface, to the northwest of the crater Coulomb, and east of van't Hoff.

Chernyshev is a lunar impact crater that is located in the northern part of the Moon's far side. It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D'Alembert.

Comstock (crater) Lunar impact crater

Comstock is a lunar impact crater that is located on the far side of the Moon. It lies to the northeast of the walled plain Fersman, and north of the crater Weyl.

Hubble (crater)

Hubble is a lunar impact crater that lies very near the east-northeastern limb of the Moon. At this location it is viewed almost from the side from Earth, and the visibility of this feature is affected by libration. It lies to the north of the Mare Marginis and northeast of the crater Cannon. About one crater diameter to the north-northeast is Lyapunov.

Comrie (crater) Lunar impact crater

Comrie is a lunar impact crater. It is located on the rugged far side of the Moon relative to the Earth, beyond the western limb. Nearby craters of note include Ohm to the south-southwest, Shternberg to the southwest, and Parenago to the northeast.

Cockcroft (crater) Lunar impact crater

Cockcroft is a lunar impact crater that is situated on the far side of the Moon from the Earth, so that it has only been observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.

Donner (crater) Lunar impact crater

Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.

Emden (crater)

Emden is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon. It is named after Jacob Robert Emden (1862-1940).

Evershed (crater) Lunar impact crater

Evershed is a lunar impact crater on the far side of the Moon, named after the English solar astronomer John Evershed. It is located to the northeast of the larger crater Cockcroft, and to the north of the smaller Van den Bergh.
