In James Cameron's Avatar, Pandora is a moon orbiting the fictional gas giant Polyphemus.
Pandora is the main setting of the 2009 science-fiction film Avatar. Humans travel there to mine unobtanium, while the Na'vi inhabit its forests and other ecosystems. The story follows Jake Sully, who uses an avatar body to interact with the Na'vi and the moon's environment.
Calling Pandora a planet is a common mistake because it has extensive landscapes, weather, wildlife, and an atmosphere shown like those of a world. Astronomically, however, the film identifies it as a moon. Its parent planet, Polyphemus, appears in the sky in several scenes.
The name connects Cameron's fictional setting with the Pandora of Greek mythology, but the film's moon is a separate creation. The ecological and cultural details belong to Avatar's fictional universe, not to the classical myth.
