What is the steepest cliff in the solar system?
The steepest cliff in the solar system is Verona Rupes, on Miranda, the moon of the outer planet of uranium. Verona Rupes is equal to 12 miles (20 km) drop. For comparison, the Grand Canyon is a cliff of 1 million and Mt. Everest is five miles tall. In astrogeology, there is a long number of mountain cliffs. Verona Rupes is a cliff named after Verona in Italy. It was named because Verona is the setting of Shakespeare's Romeo & Juliet game and the months and the features in the Urana system are traditionally named after things in Shakespearean. The cliff is even more intimidating in connection with the small month on which it is: Miranda has a diameter of only 400 km (250 miles). Some simple arithmetic shows that Verona Rupes is so deep that it will shorten to 4% of the journey to Surf Moon. A similar cliff on the ground would be 1,000 miles a deep!
The highest cliff in the solar system is not the only unusual thing that is located on the Miran surfaceDy. The whole surface is strange and jumped, with so many deep scratches, it looks like someone threw him into a blender. Scientists believe that this formula is due to intensive tectonic activity in Mirand's past caused by tidal heating in its core when its orbit has changed. The former, but now largely discounted hypothesis, was that at some point Mirand's past was hit by one or more asteroids so hard that the whole planet was detached just to condense after a few years or decades. Although it is a fantastically sounding hypothesis, scientists now consider it unlikely.
Many of them want to know: If you should jump from the top of Rupes Verona, would you survive? The answer may be yes - if you have included some padding or air. Due to the low gravity of the small month, it would take about 12 minutes to fall to the bottom. Skydiver would arrive at the bottom at a speed of about 200 km/h (125 mph), about the speed of a very fast car. ObklopeWell, a big inflated ball, that would be surviving. Size would not help slow down your descent: without atmosphere there would be no rubbing air.
Verona Rupes was discovered by Voyager 2 during his summer in Uranus in January 1986. This surface feature is too small and distant to be solved by contemporary telescopes.
