Schickard is a lunar impact crater of the form called a walled-plain. Selenographic coordinates are used to refer to locations on the surface of Earth 's Moon. Wilhelm Schickard ( April 22 1592 &ndash October 24 1635) was a German Polymath who built one of the first Calculating machines In the broadest sense the term impact crater can be applied to any depression natural or manmade resulting from the high velocity impact of a projectile with larger body 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. Drebbel is a small lunar crater that is located to the northeast of the large Schickard walled plain, in the southwestern part of the Moon. Southeast of Schickard is the Wargentin lava-flooded plateau. Wargentin is an unusual form of lunar Impact crater. The interior has been completely filled up to the edge of its raised rim by a Basaltic Lava flow so
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. The albedo of an object is the extent to which it diffusely reflects light from the sun 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.
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 Schickard crater.
