no name is ever established for the mysterious planet, but the inhabitants know of earth, venus, and mars, referring to them by name in one episode. exactly where the planet is located is also never made clear. in the episode "on a clear night you can see earth", captain steve burton (gary conway) claims to have seen earth through a set of infrared goggles invented by the giants, implying that the two planets are near enough to see one from the other. the only established method by which earth people may reach the giants' planet is high-altitude flight, passing through what one giant calls a "dimension lock".
