A junk planet, or junk world, was a type of planet that was covered in garbage and scrap, often used deliberately to store waste.
Notable junk planets[[edit] | [edit source]]
The gas giant Belannia XXI was used as a waste dump. (PROSE: Beltempest)
Endpoint was used as a dumping ground by the civilisations inhabiting its star system. This polluted its atmosphere and sea, making them acidic. After the system became caught in the crossfire of an interstellar war the survivors took refuge on Endpoint, using debris that fell onto the planet to create makeshift cities on stilts above the sea. Hope, Triumph and Persistence were among these cities. (PROSE: Hope)
The DC Mining Company once made a deal with the Travellers of Epajaenda, allowing the company to use the planet's resources and eventually turn it into a dump. At the last moment, the company's founder Abraham Derris-Cuthbertson rescinded the dumping, honouring the terms of his contract with the Travellers. (PROSE: Last Rites)
Grot was a junkyard planet where the Fourth Doctor once re-encountered Jetsam and Flotsam and helped them to stop gun-runner Joylove McShane from reactivating and taking control of a troop of Cybermen. (COMIC: Junk Yard Demon)
Junk was an interplanetary scrapyard found in the Andromeda Galaxy. Old and discarded technology was dropped off here to be sold, crushed or hurled into the sun. The planet Junk was divided into colour-coded provinces and each province was divided into lettered sections; each section was in turn looked after by a manager and a team of robots. (PROSE: Shining Darkness)
