One of the worst examples of unrealistic science (http://io9.com/367792/bad-movie-physics-a-report-card) in movies is the overly simple alien planet. Oftentimes, our heroes will visit the desert planet, or the Irish planet. But the best extraterrestrial worlds in science fiction are the ones with variety and a realistic ecosystem. They have cities as well as countryside, and a range of environments. Here's our guide to the most realistic — and interesting — planets in science fiction.
