In Avatar, what is Pandora’s parent planet called?

In Avatar, Pandora’s parent planet is called Polyphemus. Pandora is a habitable moon orbiting the gas giant in James Cameron’s science-fiction setting.

The 2009 film takes place largely on Pandora, where humans seek the valuable mineral unobtanium and encounter the Na’vi. The moon’s environment includes floating mountains, dense forests, unusual wildlife, and a biologically interconnected ecosystem. Polyphemus is visible in Pandora’s sky and establishes that Pandora is not itself a planet.

The name Polyphemus comes from the Cyclops in Greek mythology, creating another mythological connection around the film’s world. Pandora is fictional and should not be confused with Saturn’s real moon Pandora, the asteroid 55 Pandora, or the ancient Greek figure. The film’s Pandora is a moon in the Alpha Centauri star system.
