Which of these 3 distances would allow liquid water at the surface? Summary= a stars habitable zone is the range of distances around it at which a planet could potentially have surface temps that would allow for abundant liquid water A zone in which the surface temperature of a planet could allow it to have abundant liquid water on the surface . Planet size matters: e.g. the Moon is in the HZ but does not have ... Sat Oct 16 2004 · In astronomy and astrobiology the circumstellar habitable zone (CHZ) or simply the habitable zone is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. Scientists consensus is that a layer of liquid water exists beneath Europa's (moon of Jupiter) surface and that heat from tidal flexing allows the subsurface ocean to remain liquid . It is estimated that the outer crust of solid ice is approximately 10–30 km (6–19 mi) thick including a ductile "warm ice" layer which could mean that the liquid ocean underneath may be about 100 km (60 mi) … Extraterrestrial liquid water - Wikipedia Extraterrestrial liquid water - Wikipedia Extraterrestrial liquid water - Wikipedia The temperature of a planet's surface depends on the Sun's distance and luminosity and on the planet's Albedo. Proximity plus greenhouse effect determines how hot or cold the surface is rela.ve to stable liquid water . Water in its liquid form has an unusually high boiling point temperature a value close to 100°...
