Ricco is a lunar impact crater. It is located in the northern part of the Moon's far side. This crater overlays the southeastern rim of the larger Milankovic crater. Less than a crater diameter to the southwest is Karpinskiy crater. To the southeast is Roberts crater.
This is a relatively fresh crater formation that has not been degraded through impact erosion. The rim edge is well-defined except along the southwestern edge. Along that side skirt of ejecta from Karpinsky crater overlays the edge and the inner wall, reaching to the edge of the interior floor. The remainder of the inner wall has a slumped in places, forming a steep top section and shelves or terraces of slumped material. The most extensive terraces occur along the northwest side, where the rim overlays part of Milankovic crater. The outer rampart of Ricco spills over to form a pile covering a quarter of the interior of Milankovic's floor.
The interior floor of Ricco has level patches surrounding a formation of ridges about the mid-point. The most prominent of these ridges lies along the northeast side of the mid-point. There is a smaller ridge to the south and a low ridge in the northern floor. Several low hills lie across the crater floor.
