In the Avatar universe, Pandora is a moon of which fictional planet?

In the Avatar universe, Pandora is a moon of the fictional planet Polyphemus.

James Cameron’s Avatar presents Pandora as a habitable moon in the Alpha Centauri star system. It is the setting for the 2009 film and its sequels, including The Way of Water. The moon’s forests, floating mountains, oceans, and native Na’vi culture are central to the story.

Polyphemus is a gas giant, and Pandora is one of its moons. This detail is sometimes missed because the films focus on Pandora rather than showing much of its parent planet. Pandora is also easily confused with the real Saturnian moon of the same name, but the two objects belong to entirely different fictional and scientific contexts.

The Avatar setting uses familiar astronomical ideas, such as a moon orbiting a giant planet, while adding fictional biology and geography. Pandora’s dense atmosphere and life-supporting environment are elements of the series’ imagined world rather than observations about Saturn’s real moon.
