Censorinus is a 3.8 km lunar impact crater located on a rise to the southeast of the Mare Tranquillitatis. It is named after the ancient Roman writer Censorinus. [1] To the northeast is the crater Maskelyne.

Contents

Censorinus is distinguished by an area of high-albedo material surrounding the rim. This makes the feature highly prominent when the Sun is at a high angle, and it is one of the brightest objects on the visible Moon. Bright streaks radiate away radially from the crater, and contrast with the darker lunar mare.

This formation has a sharp-edged, raised rim and a symmetrical, cup-shaped interior. Close-up photographs of this crater by Lunar Orbiter 5 show many large blocks lying along the sloping outer rampart. The surface near the crater is hummocky from the deposited ejecta. The crater is otherwise undistinguished.

The vicinity of Censorinus was once considered for an early Apollo landing site. [2] [3]

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 Censorinus.

Aryabhata, named after Indian astronomer Aryabhata, is the remnant of a lunar impact crater located in the eastern Mare Tranquillitatis. The crater has been almost submerged by lava-flow, and now only an arc-shaped ridge formed from the eastern half of the rim remains above the lunar mare. This crater was previously identified as Maskelyne E before being named by the IAU in 1979. Maskelyne itself is to the southwest.

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

Abbot is a small lunar impact crater that lies on the rugged ground between the Mare Fecunditatis in the south and west, and the Mare Crisium to the north. It is a circular crater with a cup-shaped interior. The inner walls slope downward to the midpoint, and no impacts of significant mark the interior or the rim.

Egede is the remains of a lunar impact crater that has been flooded by lava, leaving only the somewhat polygonal circumference of the rim protruding just above the mare. It was named after Dano-Norwegian natural historian Hans Egede. It is located on the southern edge of the Mare Frigoris, to the west of the crater Aristoteles. To the southwest is an arc of low mountains curving between the rims of Aristoteles and Eudoxus. The floor of Egede is flat and nearly featureless, except for a few tiny craterlets, including secondaries from Aristoteles. The surviving rim has a maximum altitude of 0.4 km above the surface.

Bohnenberger is a lunar impact crater that lies near the east edge of the Mare Nectaris, in the foothills of the Montes Pyrenaeus mountain range that forms the perimeter of the mare. To the east beyond the mountains is the larger crater Colombo. The crater has a low rim along the north wall, and the floor is somewhat irregular with a ridge crossing the floor. There is a small crater along the western inner wall.
