 In the radio show, Krypton was part of our Solar System, a Counter-Earth sharing Earth's orbit but on the opposite side of the Sun, hidden from view of the Earth ("Krypton" derives from the Greek word for "hidden").Some comics of the early 1950s suggested a similar theory, but in general the comics have depicted Krypton as being in a far-away star system.In the first feature-length "Superman" film in 1978, a vastly less idyllic image of Krypton was presented.
