Astronomy Picture of the Day - 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.

Yes I noticed the face looked like a vertical fault.

In your post number 9 it shows a height in the 30,000 ft range. But, isn't 20km a bit over 60,000 ft? That would be a difficult climb. Especially with no atmosphere!

You posted a picture of horsts and grabens. Grabens are the down parts.

After the previous post containing the graph of the Verona Rupes cliffs shown to be less than 35000 ft, I was going to post that the Marianas Trench is at least 36,037 ft.

Yes, that graphic I posted does seem to be at odds with the article you posted. 20km is actually just over 65,000 ft. Don't know why. Maybe the graphic was based on older data and estimates.

Yes, who knows how they measured it. They may not have corrected for low temperature contraction on the tape measure they used.
