Eponym | Irvine C. Gardner |
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.
