Known and Unknown

It might be possible to describe Saturn’s moon Hyperion as an oddball, if it were a ball at all. It is the largest object in the Solar System that is not, at least approximately, a sphere. For anything else of the same size, gravity has pulled and crushed material so that surface irregularities are small compared with the whole body. But Hyperion is one big irregularity, in every way.
