Verona Rupes, right of center,[2] photographed by Voyager 2 in January 1986.

Verona Rupes is a cliff on Miranda, a moon of Uranus.[3] It was discovered by the Voyager 2 space probe in January 1986. The cliff face, previously thought to be from 5 to 10 km (3 to 6 mi)[4] high, is currently estimated to be 20 km (12 mi)[5] high as of 2016, which makes it the tallest known cliff in the Solar System.[6]

It may have been created by a major impact, which caused the moon to disrupt and reassemble,[3][6] or by the crust rifting.[7]

Given Miranda's low gravity, it would take about 12 minutes to fall from the top, reaching the bottom at the speed of about 200 km/h.[5]
