Planetary climatology

Definition

Planetary climatology is the study of the climate systems of planets other than Earth, focusing on understanding the atmospheric conditions, weather patterns, and long-term climate behavior of these celestial bodies. This field integrates knowledge from various disciplines, including geology, atmospheric science, and astronomy, to explore how different factors like solar radiation, planetary composition, and orbital mechanics affect climate. By examining climates on other planets, scientists can gain insights into climate change and potential habitability beyond Earth.
