Jupiter has 12 new moons — including one really weird one

Astronomers have discovered 12 new moons in orbit around Jupiter, the largest planet of our solar system. Of the newly-discovered moons, the oddest is a small rocky world dubbed "Valetudo." Just one kilometer across, Valetudo goes "the wrong way" and could one day smash into one of its neighbours.
