Space station

An inhabited structure constructed or meant for permanent use outside the atmosphere of any planet or star, space stations are usually situated in a fixed orbit. Space stations are contrasted with spaceships and starships, which are intended to move under their own power between planets or star systems, wheras space stations are usually limited to attitude adjustment or slow movement. Notable examples from reality include Mir, Skylab, and the International Space Station. Examples from fiction include Babylon 5, Deep Space 9, K-7, Ty'Go'kor, and Kuat Drive Yards.
