Tallest Cliff In The Solar System Mar 23

If we were to drop a bowling ball from the top (something you should never ever do), it would take almost 20 seconds for it to hit the ground. Count that out in your head: 1 … 2 … 3 … 4 … . That’s a lot of falling! By the time it reaches the ground, the ball would be traveling over 150 miles per hour! That would be a pretty extreme fall for a professional cliff jumper.

Not impressed? Fine. But the tallest cliff known to us is in a place even more remote than northern Canada. We would have to take a long journey to find it.

It’s on a moon named Miranda in orbit around Uranus. That’s right near the far edge of our solar system. It’s estimated that this cliff—named Verona Rupes—is over six miles high. It’s nearly 33,000 feet tall. That’s five times the depth of the Grand Canyon and taller than Mount Everest!

But what might shock you is how long it would take. The fall would last a full eight minutes. You might also be surprised to learn that the jumper would be going much slower by the time he or she reached the ground. The jumper would max out at around only 90 miles per hour and might even be able to land safely with some sort of futuristic airbag!

The fall would take so much more time because Miranda is much smaller than Earth. That means it has less gravity. In fact, the gravity is only 0.008 times as strong there as compared to Earth.

So maybe our super long space jump wouldn’t be that extreme after all?
