Pandora is an Earth-like, habitable, extrasolar moon from Alpha Centauri. It's the 5th moon of the gas giant Polyphemus, which orbits Alpha Centauri A. It has an unbreathable atmosphere, less extreme temperatures, and few dark nights. Its animals are fundamentally different to humans, and it has a humanoid species called the Na'Vi, who are a relatively peaceful, minimalist people, though they're very intelligent and capable of fighting back in case of hostilities. Most things are bioluminescent.
