Rupes Cauchy

Rupes Cauchy, photographed by Apollo 8

Rupes Cauchy is a 120km-long escarpment at 9°00′N 37°00′E / 9.0°N 37.0°E on the surface of the Moon. It faces southwest, and rises about 200-300 m.[1] It is located in the northeastern portion of the Mare Tranquillitatis, and is named after the nearby crater Cauchy.

Rupes Cauchy casts a thin shadow about five days after the new moon, when the sunrise terminator is nearby and the sunlight is arriving at a low angle.[2]
