Less than one crater diameter to the southwest is Karpinskiy, while to the southeast is Roberts.

This is a relatively fresh crater formation that has not been degraded through impact erosion.

The most extensive terraces occur along the northwestern side, where the rim overlays part of Milankovic.

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 midpoint.
