Andromeda (constellation)

Andromeda was a constellation. People from the constellation were called Andromedans, though this was a, not a species. Beings from several different planets, such as Salostopus, could be correctly called "Andromedans".

The constellation was remote enough to require suspended animation for the space journey to Earth. Andromedan astronauts were therefore sometimes called "sleepers". (TV: The Trial of a Time Lord; PROSE: The Mysterious Planet, The Ultimate Foe)

The Sixth Doctor may have been referring to the constellation when he once waxed poetic about the beauty of "Andromeda", or he may have been talking about the galaxy of the same name. In either case, Peri thought the description distastefully reminiscent of the Eye of Orion. (TV: Timelash)
