Due to the importance of liquid water to Earth's [[biosphere]], the [[planetary habitability|nature of the CHZ]] and the objects within it may be instrumental in determining the scope and distribution of 
planets capable of supporting Earth-like [[extraterrestrial life]] and [[extraterrestrial intelligence|intelligence]].

The habitable zone is also called the '''Goldilocks zone''', a metaphor of the children's [[fairy tale]] of "[[Goldilocks and the Three Bears]]", in which a little girl chooses from sets of three items, ignoring the ones that are too extreme (large or small, hot or cold, etc.), and settling on the one in the middle, which is "just right".
