Junk
From Tardis Wiki, the free Doctor Who reference
Junk is an interplanetary scrap yard found in the Andromeda Galaxy. Old and discarded technology is dropped off here to be sold or crushed and hurled into the sun. It is divided into colour coded provinces and each province is divided into lettered sections; with each being looked after by a manager and a team of robots. The Doctor and Donna visited greeny-yellow province (sector J) and met general manager 77141 and the robots Chuck and Crusher during their trip to the Andromeda Galaxy. (TDA: Shining Darkness).
