Eponym	Wilhelm Schickard

Schickard is a lunar impact crater of the form called a walled-plain. It lies in the southwest sector of the moon, near the lunar limb. As a result the crater appears oblong due to foreshortening. Attached to the northern rim is the lesser Lehmann crater, and to the northeast is the even smaller Drebbel crater. Southeast of Schickard is the Wargentin lava-flooded plateau.

The Schickard crater has a worn rim that is overlaid in several locations by smaller impact craters. The most prominent of these is irregular Schickard E crater across the southeast rim. The Schickard crater floor has been partially flooded by crater, leaving only the southwest portion uncovered and rough-textured.

The floor is marked with a triangular band of lighter-albedo material, leaving relatively darker patches in the north and southeast. This feature is more prominent when the sun is at a relatively high angle. There are also multiple small crater impacts on the floor, most notably in the southeast.

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 Schickard crater.
