Habitable Zone Calculator
From Star Luminosity
HZ = sqrt(L) * zone factor
Formula
HZ inner = 0.95 * sqrt(L) AU | HZ outer = 1.37 * sqrt(L) AU
Frequently Asked Questions
What is the habitable zone?
The habitable zone is the region around a star where liquid water could exist on a planet surface. For the Sun it is roughly 0.95 to 1.37 AU.
What are conservative vs optimistic estimates?
Conservative estimates use stricter climate models. Optimistic estimates allow for greenhouse warming and other factors that could extend the zone.
