Nope. Pandora is about ten times as big as Earth--or at least rotates on its axis about ten times slower. Trailers and articles (found on youtube or in Game Informer, etc.) have stated that, after 7 years of human occupation of Pandora, the planet is turning to spring, and the vicious creatures that were hibernating are now coming out and terrorizing the human populace. It can be assumed that Pandora is about tentimes as big as Earth.
