The Goldilocks zone is a Tau'ri term used to describe an area of a star system for which a planet can support Human life would be situated. The zone is an area where the planet is far enough away from the system's star so that it is not too hot and not far enough out that it would be too cold. It is named after the fairy tale Goldilocks. The Goldilocks zone planet, visited in 2009 by the Destiny expedition, was named after this term. (SGU: "Light")
