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. Just to the northeast of the crater is the dome-like Mons Maraldi rise.
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 mid-point, and several tiny craters mark the floor surface.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Maraldi.
