In James Cameron’s Avatar, what giant planet does Pandora orbit?

In James Cameron’s Avatar, Pandora orbits the giant planet Polyphemus.

Pandora is a fictional moon in the Avatar universe, not a planet. It is depicted as a lush world inhabited by the Na’vi and numerous other species. The moon’s dense forests, floating mountains, and unusual biological network form the setting for the 2009 film Avatar.

Polyphemus is a gas giant located in the Alpha Centauri system. Pandora’s position as a moon helps explain why the film shows the enormous planet prominently in its sky. The fictional astronomy gives the setting a planetary environment while preserving the visual drama of a nearby giant world.

Pandora is also frequently confused with the real exoplanets or moons used in science-fiction comparisons. It has no confirmed real-world counterpart. The name refers to Cameron’s fictional setting, while Polyphemus identifies the larger body around which the moon travels.
