Peek is a small lunar impact crater that is located in the northern part of the Mare Smythii near the eastern limb of the Moon.

Even when visible, however, the crater is seen almost edge-on, making it difficult to see much detail from the Earth.

Due to foreshortening the crater appears close to Schubert, even though the two are about 60 km apart.

This crater is generally circular and bowl-shaped, with a small interior floor at the center of the sloping inner walls.

The crater has a higher albedo than the surrounding dark lunar mare, making it appear slightly brighter than the nearby terrain.
