The strangest moon in the Solar System

A short but interesting article covering the many strange aspects of Saturn’s Iapetus

Cassini made many great discoveries about this planet, including the divisions between the rings and a number of Saturn’s moons. In fact, the second of Saturn’s moons ever discovered, Iapetus, presented a tremendous mystery to Cassini. While it clearly orbited Saturn like the other moons, it was only visible during half its orbit, remaining completely invisible during the other half.

It would take three centuries and an unmanned spacecraft named in his honor to figure out why.
