Planetary research is a branch of astronomy that focuses on the study of planets within our solar system and beyond. This field explores the composition, geology, atmospheres, and potential habitability of planets, as well as their formation and evolution. Researchers use a variety of tools and techniques, such as telescopes, spacecraft missions, and computer simulations, to gather data and analyze planetary systems. The ultimate goal of planetary research is to deepen our understanding of the origins and characteristics of planets, and to shed light on the possibilities of life beyond Earth.
