In James Cameron’s Avatar, what is the name of Pandora’s parent planet?

In James Cameron’s Avatar, Pandora’s parent planet is named Polyphemus.

Pandora is a fictional habitable moon orbiting the gas giant Polyphemus in the Alpha Centauri star system. The moon is the main setting of Cameron’s 2009 science-fiction film, where humans seek the valuable mineral unobtanium and encounter the Na’vi.

Because Pandora is a moon rather than a planet, the film’s setting is sometimes described imprecisely as a planet. The distinction matters: Polyphemus is the larger planetary body, while Pandora is the world explored by the human and Na’vi characters.

This fictional system is separate from Saturn’s real moon Pandora and from the mythological figure. The shared name is deliberate, but the film’s Pandora belongs to a speculative astronomical setting created for the Avatar universe.
