Verona Rupes is the tallest known cliff on Miranda, a moon of Uranus. It was discovered by the Voyager 2 space probe in January 1986. Its name was adopted by the International Astronomical Union (IAU) in 1988, named after the city of Verona, which is set in Romeo and Juliet, written by William Shakespeare.[2] It may have been created by a major impact that caused the moon to disrupt and reassemble,[6][7] or by the crust rifting.[8] Given Miranda's low gravity, it would take about 12 minutes to fall from the top, reaching the bottom at a speed of about 200 km/h.[5]
There are many estimates about the cliff's height. It was thought to be from 5 to 10 km (3 to 6 mi)[4] high, while another estimated to be 20 km (12 mi),[5] which makes it the tallest known cliff in the Solar System. One study estimated that the "true" depth of Verona Rupes is around 5 to 15 km (3 to 9 mi) when not accounting for oblique viewing caused by parallax, gradually getting more shallower towards the terminator.[3] It may be presumed that the scrap extends beyond the terminator in the northern hemisphere, in which the Voyager 2 probe cannot view farther than.[9] The scarp's slope with regard to the dark limb that extends past the terminator is estimated to be around 25 to 30 degrees.[3]
