Steinheil is a lunar impact crater that is located in the rugged highlands in the southeastern part of the Moon. It forms a prominent crater pair with the similar-sized Watt crater, which it partly overlays to the southeast. To the northwest is the large Janssen walled-plain. Due to the location of this crater, it appears foreshortened when viewed from the Earth.[1] It is from the Nectarian period, 3.92 to 3.85 billion years ago.[2]
This is a relatively circular crater that has undergone some light erosion from subsequent impacts. The inner wall is wider along the southwestern rim than elsewhere, and there is a slight outward bulge in the western rim. There are a few tiny craterlets along the rim and inner wall, the most notable being a crater at the base of the inner northeast rim. The interior floor is level, with no central peak and only a few minor craterlets.[2]
[edit] 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 Steinheil crater.[3]
