A common item of sf Terminology, denoting a planet in the galactic rim region (see Galactic Lens). Rimworlds are of importance in John Brunner's Interstellar Empire sequence and provide the various settings of A Bertram Chandler's John Grimes/Rim World stories. Probably the most notable individual rimworld in sf is Terminus in the Foundation trilogy by Isaac Asimov, which is selected as the home of the eponymous Foundation because of its extreme remoteness from the core of Galactic Empire.
