Which of the following best describes habitable zone?
habitable zone the orbital region around a star in which an Earth-like planet can possess liquid water on its surface and possibly support life. Liquid water is essential to all life on Earth and so the definition of a habitable zone is based on the hypothesis that extraterrestrial life would share this requirement.
How do you know if a planet is habitable?
For a planet/moon/asteroid to be considered habitable, it must orbit in a zone where liquid water is possible. The planet needs to be far enough away from the star that the surface water does not evaporate and close enough to the star that the surface water does not remain perpetually frozen.
Is Earth the only habitable planet?
Because Earth is the only known inhabited planet and its life depends on liquid water, efforts to identify exoplanets that could host life focus on Earth-like worlds.
