Discovery Rupes is an escarpment on Mercury, approximately 267 kilometers (166 mi) long, located at latitude 58.52 N and longitude 53.25 W.[1] It was formed by a thrust fault, thought to have occurred due to the shrinkage of the planet's core as it cooled over time. The scarp cuts through Duccio crater.
