Fechner (crater)

Fechner is a lunar impact crater that lies on the far side of the Moon's southern hemisphere, attached to the western rim of the large walled plain Planck. 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 northwards from the periphery of the northeast rim.

EponymGustav T. Fechner
Apollo 8 photographed Fechner from a distance. Fechner T is the bright crater above center.

Attached to the western rim of Fechner is Fechner T, a small, bowl-shaped crater with a relatively high albedo ray system. This satellite crater 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 Planck. The interior floor is marked by several small craters.

The crater is named after Gustav Theodor Fechner, a German physicist, psychologist, and philosopher (1801-1887). The name was approved by the IAU in 1970.[1]

Satellite craters

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

gollark: Try geckos. Most people haven't had experience with geckos chasing them.

gollark: But it already has gone up to the "definitely really bad" bit in some regions.
