Stiborius is a lunar impact crater that lies to the south-southwest of the crater Piccolomini, in the southeastern quadrant of the Moon's near side. To the south-southwest of Stiborius is the smaller Wöhler. Stiborius is 44 kilometers in diameter and 3.7 kilometers deep.[1]

EponymAndreas Stöberl

The rim of this crater is well-defined with little appearance of erosion. It is roughly circular in form, but has a prominent outward bulge to the northeast where the side has slumped into the interior. There is a terrace-like shelf along the southeastern and northern inner walls. The interior floor is somewhat irregular, and there is a low central peak at the midpoint that is connected to the northeastern wall by a low ridge.[2] It is from the Upper Imbrian period, 3.8 to 3.2 billion years ago.[3] It is named after Andreas Stöberl, a 15th-century philosopher, theologian, and astronomer.[1][4]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Stiborius.[5]
