SUMMARY: Although the Kuiper Belt, a region of icy objects located past the orbit of Neptune, was only discovered in 1992, it's already presented a host of mysteries. One mystery is why an unusually large number of these objects have small satellites orbiting them - 8 out of the 500 objects discovered so far have had satellites. The high number brings into question the traditional theory that they're caused by collisions.

What do you think about this story? Post your comments below.

What's so big and bad about 8 of 500? In the asteroid belt alone, I'm sure there's tens of such satellite systems, including the Ida-Dactyl system.

What alternative theories, if any, have been put forward?
