|Eponym||Richard A. Proctor, a British astronomer (1837–1888)|
Proctor is a large crater in the Noachis quadrangle of Mars, located at 48° south latitude and 330.5° west longitude. It measures 168.2 kilometres (104.5 miles) in diameter and was named after Richard A. Proctor, a British astronomer (1837–1888).
The crater contains a 35 x 65 km dark dune field. It was one of the first sand dune fields ever recognized on Mars based on Mariner 9 images. The crater's dunes are being monitored by HiRISE to identify changes over time.
