Webb is a small lunar impact crater that is located near the eastern edge of the Mare Fecunditatis, in the eastern part of the Moon near the equator. It is to the north of the prominent Langrenus crater, and west of Maclaurin crater.
The interior of Webb crater is relatively dark compared to the inner walls of the rim, and it has a low hill at the mid-point of the interior. On the lunar mare to the north is a faint marking of a ray system that appears to radiate from this crater.
[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 Webb crater.
