Saturn's Moon Iapetus Has A 'Belt'

Believe writes "In another unexpected find by Cassini-Huygens, Saturn's moon Iapetus shows a bulging waistline. According to the story, the dark side of the moon is almost perfectly bisected by a tall, narrow ridge that runs for 1300 km (808 mi) and rises up to 20 km (12 mi) high. This height is amazing in such a small moon; it rivals Olympus Mons on Mars which is a body 5 times its size."

    One remaining option is impact by a large asteroid. We now have to come up with a reasonable impact scenario that can produce a feature similar to the one seen on Iapetus, which is indeed very strange.

    Easy: two big asteroids struck the moon simultaneously on both poles!

    The Death Star had other features that this moon presently lacks.

    Oh come on. Give it a break. It was built a long time ago in a galaxy far, far away. It has a lot of miles and a lot of years on it. I think it looks good for its age.

    When 4 billion years you become, look as good you will not.
