Apianus (crater)
Description
The outer wall of the crater has been worn and eroded by subsequent impacts, and a pair of small craterlets overlay the rim to the southeast and northeast. The central crater is 63 kilometers in diameter and 2,080 meters deep. The craterlet on the southeast rim, Apianus B, is a member of a cluster of co-joined craterlets that includes Apianus T and Apianus U. The interior floor of the central crater is relatively smooth and lacks a central peak, although the surface appears somewhat convex. Only a few tiny craterlets mark the surface.
The crater is from the Nectarian period, 3.92 to 3.85 billion years ago.

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