Etymology
Tyche was later used as the name for a suggested distant planet because, like the goddess, it was thought to control the 'luck' of comets and strange orbits, so a hidden world might explain odd comet paths. So calling that planet Tyche links the scientific idea to the old image of a force that shapes chance.
