Seyfert is a prominent lunar impact crater that is located on the far side of the Moon.

Just to the north of Seyfert is the crater Harriot and equally close to the south is Polzunov.

The interior floor of Seyfert is relatively level, and is marked by a number of tiny craterlets.

Traces of the ray system from Giordano Bruno to the northwest lie along the rim and interior floor of Seyfert.

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