Maraldi is a worn, eroded crater on the western edge of the Sinus Amoris, in the northeast part of the Moon. To the west-southwest is the crater Vitruvius, and to the northwest lies the worn Littrow crater. Just to the northeast of the crater is the dome-like Mons Maraldi rise.
The crater is named after two Italian-born French astronomers: Giovanni Domenico Maraldi and Giacomo F. Maraldi.[1]
Maraldi has a very worn outer wall that is deeply incised and has the appearance of a circular range of peaks rather than a crater rim. The interior has been flooded with basaltic lava, leaving a flat surface with a low albedo. There is a low ridge just to the northwest of the midpoint, and several tiny craters mark the floor surface.
Maraldi is a crater of Nectarian age.[2]
Satellite craters[edit]
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Maraldi.
