Therefore, only about a third of the known "habitable" planets, of which scientists have discovered about 4,000, could sustain complex life forms like us. Based on what we’ve observed in our own solar system, large, gaseous worlds like Jupiter seem far less likely to offer habitable conditions. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. Many rocky planets have been detected in Earth’s size-range: a point in favor of possible life.

We can tell if a planet is in the habitable zone based on the distance of the planet from its host star and the temperature of that star. It lies somewhat closer to its star than Venus does to the sun and thus revolves faster than Earth.
