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 crater Langrenus, and west of Maclaurin and the smaller Hargreaves, it is also north-northeast of Naonobu.

Satellite craters of Webb

The interior of Webb is relatively dark compared with the inner walls of the rim, and it has a low hill at the midpoint 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.

West of the crater is a wrinkle ridge known as Dorsa Andrusov.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Webb. Three of its satellite craters are larger than itself, Webb P located to the northwest is partly a ghost crater in its south, also Webb C located in the east is largely a ghost crater.
