In James Cameron’s 2009 film Avatar, Pandora is a moon.
The fictional Pandora orbits the gas giant Polyphemus in the Alpha Centauri star system. It is the primary setting of the film and home to the Na’vi, the tall blue humanoid inhabitants whose culture and environment drive the story.
Calling Pandora a moon rather than a planet is a specific detail of the film’s setting. The movie presents its forests, floating mountains, wildlife, and atmospheric conditions as parts of a complex extraterrestrial ecosystem. The fictional world is unrelated to Saturn’s real moon Pandora.
Avatar premiered in 2009 and became known for its extensive use of computer-generated imagery and 3D filmmaking. Its Pandora is also distinct from the music and audiobook subscription company that uses the same name.
