Gardner is a small lunar impact crater in the northeast part of the Moon. It was named after an American physicist Irvine Clifton Gardner in 1976. [1] It lies due east of the crater Vitruvius, in a section of rough terrain north of the Mare Tranquillitatis. Gardner was previously designated Vitruvius A before being given its present name by the IAU. To the northeast of Gardner is the larger crater Maraldi.

It is a circular crater with sloping inner walls and an interior floor that occupies about half the total crater diameter. The southern half of the floor has a slight rise before reaching the inner wall. The crater is not significantly eroded, and the outer rim is relatively sharp and well-defined. The most distinctive feature is a row of four rounded hills along the northern floor of the crater.

To the south is an elevated area unofficially known as the Gardner Megadome. [2] In the vicinity of the dome are satellite craters including Vitruvius B, H, and T, and Maraldi D.

Wallace is the remains of a lunar impact crater that has been flooded by lava. It was named after British natural historian Alfred Russel Wallace. It lies in the southeastern part of Mare Imbrium, northeast of the crater Eratosthenes. The crater rim forms a somewhat polygonal outline, and is broken in the southeast. The floor is flat and devoid of significant features, but it is overlain by ray material from Copernicus to the southwest. The rim ascends to an altitude of 0.4 km above the lunar mare.

<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.
