Pandora is a forest moon of the gas planet Polyphemus that is inhabited by the Na`vi , a tall, blue, tailed humanoid race form. Pandora`s atmosphere is unsuitable for humans to breathe naturally so humans are being merged with their avatars to enable them to communicate with Na`vi. Pandora has large boulders suspended in mid-air. In World of Warcraft, Pandora`s atmosphere is similar to Nagrand. The planet is one of thirteen that orbit a larger gas planet Polyphemus. The planet is of interest to Earth because of large quantities of unobtanium, a material that is capable of producing large amount of energy which Earth needs. Pandora is described as being in the Alpha Centauri A solar system.
