Pluto's largest satellite (6)

I believe the answer is:

charon

(Other definitions for charon that I've seen before include "In Greek myth, ferryman of Hades" , "Mythical ferryman of the river Styx" , "Ferryman of dead (Gk. myth)" , "Hell's mythical boatman" , "Ferryman who brought the souls of the dead across the river Styx" .)

I've seen this clue in The Times.
