Planet formation is the scientific study of the processes by which planets are formed in planetary systems, such as our own Solar System. This research area covers the initial stages of planetary formation, from the aggregation of dust particles in protoplanetary disks to the formation of planetesimals, protoplanets, and eventually fully formed planets. Researchers in this field study the physical and chemical processes involved in planet formation, including the role of gravity, collisions, and accretion in shaping the structure and composition of a developing planet. They also investigate the environmental conditions within protoplanetary disks, such as temperature, pressure, and composition, that influence the formation and evolution of planets. By studying planet formation, scientists aim to better understand the diversity of planetary systems in the universe, including the range of sizes, compositions, orbits, and other characteristics of planets. This research also helps to shed light on the origins of our own Solar System and the conditions that led to the formation of Earth and other planets.
