[[File:Diagram of different habitable zone regions by Chester Harman.jpg|thumb|300x300px|A diagram depicting the Hhabitable Zzone (HZ) boundaries around stars, and how the boundaries are affected by [[Stellar classification|star type]]. This new plot includes [[Solar System|solar system]] planets ([[Venus]], [[Earth]], and [[Mars]]) as well as especially significant [[exoplanet]]s such as [[TRAPPIST-1d]], [[Kepler-186f]], and our nearest neighbor [[Proxima Centauri b]].]]

In [[astronomy]] and [[astrobiology]], the '''circumstellar habitable zone''' ('''CHZ'''), or simply the '''habitable zone''', is the range of [[orbit]]s around a [[star]] within which a   [[planetary surface]]   can support [[liquid water]] given sufficient [[atmospheric pressure]].<ref>Su-Shu Huang, American Scientist 47, 3, pp. 397- –402 (1959)</ref><ref name=dole-1964>{{cite book |url=https://www.rand.org/pubs/commercial_books/CB179-1.html |title=Habitable Planets for Man |publisher=Blaisdell Publishing Company |author=Dole, last=Dole first=Stephen H. |date=1964 |page=103}}</ref><ref name="F.
