Tags: Crater.
Riccius is a lunar crater that is located in the rugged southeastern part of the Moon’s near side. It lies within one crater diameter southeast of the crater Rabbi Levi. To the east-northeast is Stiborius and due south is Nicolai.This formation has been so heavily bombarded by subsequent impacts that it is nearly unrecognizable as a crater. Only the western and southwestern parts of the rim remains intact the remainder having been completely obliterated by small craters.
