Habitable zone, or circumstellar habitable zone (CHZ) is a term in astronomy and astrobiology, that refers to the range of orbits around a star which are based on Earth's position to the Sun. Calculations for a star system's CHZ is contingent to the amount of radiant energy Earth receives from the Sun in the Solar System, to hypothetically support a planetary surface with liquid water and sufficient atmospheric pressure for life.[1][2][3][4][5]
