Herschel is a lunar impact crater located just to the north of the walled plain Ptolemaeus. Just to the north is the flooded crater Spörer, and due east lies the disintegrated crater Gyldén. About a crater diameter to the northwest is the walled plain Flammarion, along the southern edge of the Sinus Medii.

The rim of this crater is generally circular, although the western side is straight. It has a well-defined edge that is not significantly worn, and the inner walls are terraced. On the rough inner floor is a notable central rise. This peak is offset slightly to the west of the crater midpoint. The small crater Herschel G is attached to the south-southwest rim, and a tiny craterlet lies across the southern rim.

Satellite craters[edit]

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