Passage to Pluto is a juvenile science fiction novel, the fourteenth in Hugh Walters' Chris Godfrey of U.N.E.X.A.

It was the last of the series to have a cover illustration by Leslie Wood.

Chris Godfrey is now deputy-director of UNEXA; he sends his former crew-mates to investigate unexplained perturbations in the orbit of Pluto.

This was the last of Hugh Walters' 'exploration' novels as his realistic approach could not envisage travel further afield.
