In the film Avatar, most of the story takes place on the moon Pandora.
James Cameron’s 2009 science-fiction film follows humans and the Na’vi on Pandora, a habitable moon orbiting the fictional gas giant Polyphemus in the Alpha Centauri star system. The moon’s forests, floating mountains, wildlife, and luminous ecosystem form the film’s central visual and ecological setting.
Pandora is not presented as a planet in the film’s fictional astronomy. It is a moon with a breathable atmosphere for the Na’vi but toxic air for humans, which is why human characters use masks outside their controlled bases. The story also focuses on unobtanium mining and the conflict between the Resources Development Administration and the Na’vi.
The name deliberately recalls the Greek myth, but the film’s Pandora is an invented extraterrestrial world rather than the mythological woman’s container. Avatar became a major global box-office success and led to a series of planned and released sequels set in the same fictional universe.
