Habitable Zones & Planetary Climate: Observation, Measurement & Evidence

The circumstellar habitable zone is the range of orbital distances where a rocky planet with an appropriate atmosphere could maintain liquid water on its surface. Habitable zones prioritize targets for atmospheric characterization and frame studies of climate stability, stellar evolution, and the conditions needed for surface liquid water.

Climate reflects the balance between absorbed stellar energy and outgoing thermal radiation, modified by greenhouse absorption, albedo, heat transport, clouds, and atmospheric circulation.
