            Verona Rupes: Tallest Known Cliff in the Solar System

   Explanation: Could you survive a jump off the tallest cliff in the
   Solar System? Quite possibly. Verona Rupes on Uranus' moon Miranda is
   estimated to be 20 kilometers deep -- ten times the depth of the
   Earth's Grand Canyon. Given Miranda's low gravity, it would take about
   12 minutes for a thrill-seeking adventurer to fall from the top,
   reaching the bottom at the speed of a racecar -- about 200 kilometers
   per hour. Even so, the fall might be survivable given proper airbag
   protection. The featured image of Verona Rupes was captured by the
   passing Voyager 2 robotic spacecraft in 1986. How the giant cliff was
   created remains unknown, but is possibly related to a large impact or
   tectonic surface motion.
