What is the name of the fictional moon where Avatar is set?

Pandora is the fictional moon where James Cameron’s Avatar is set.

Avatar, released in 2009, takes place primarily on Pandora, a lush moon orbiting the fictional gas giant Polyphemus in the Alpha Centauri system. The moon is home to the Na’vi, a tall blue humanoid species whose culture is closely connected to Pandora’s living environment.

The film follows former Marine Jake Sully, who operates an avatar body while humans seek resources on the moon. Its setting uses the mythological name as a science-fiction world rather than as a direct retelling of the Greek story.

Pandora is sometimes called a planet in casual discussion, but the film identifies it as a moon. The name also links the film to a wider cultural tradition in which Pandora symbolizes discovery, danger, and the consequences of opening something unknown.
