It was named after British astronomer Thomas William Webb.
[1] It is to the north of the prominent crater Langrenus, and west of Maclaurin.
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 the wrinkle ridge Dorsa Andrusov.
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.
