Eponym	Gustav T. Fechner

Fechner is a lunar crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large Planck walled-plain. The eastern rim of Fechner intersects the Vallis Planck, a long, wide cleft in the surface that follows a course to the north-northwest. This valley intrudes into the southeastern rim of the crater, then continues northward from the periphery of the northeast rim.

Attached to the western rim of Fechner is a small, bowl-shaped crater with a relatively high albedo. This satellite crater 'Fechner C' is surrounded by a blanket of light-hued ejecta that spills across the southwestern half of Fechner's interior floor. The crater rim of Fechner is relatively worn and eroded, with the eastern half of the rim reshaped due to the valley and proximity to the Planck crater. The interior floor is marked by several tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Fechner crater.
