Derelict (Alien)

The Derelict is the name given to the abandoned alien spacecraft discovered by the crew of the deep space tug Nostromo in the 1979 science fiction film Alien. The Derelict was built by a species that have become known as The Space Jockeys. It was investigated by the Nostromo crew in response to a mistaken SOS signal originating from its location, LV-426, a fictitious moon (frequently but erroneously referred to as a planet) in the Zeta II Reticuli system.
