'''Riccioli''' is a large
moon lunar impact crater located near the western limb of the
Moon. It lies just to the northwest of the even larger and more prominent
Grimaldi (crater) Grimaldi crater. To the southwest are the
Hartwig (lunar crater) Hartwig and
Schlüter (crater) Schlüter craters that lie on the northeast edge of Montes Cordillera, the ring-shaped range that surrounds
Mare Orientale. Due to its location, the Riccioli crater appears strongly foreshortened and is viewed almost from the side.
The Riccioli crater has been heavily worn and eroded, most notably by ''ejecta'' from the impact that created the Orientale basin. This debris has created radial features toward the northeast. The ''ejecta'' has accumulated in ridges that are traverse to the radial features, particularly in the northeast section of the floor. In the northern half of the interior, the dark covering of
lava that previously resurfaced the floor is still visible. A system of
rilles named the ''Rimae Riccioli'' lies across the interior, and is still visible despite the deposited ''ejecta''.
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 Riccioli crater.
