Planetary Evolution refers to the processes and changes that shape the formation and development of planets over time. This concept encompasses the physical, chemical, and geological transformations that occur from a planet’s initial formation in a protoplanetary disk to its current state. It includes the processes of accretion, differentiation, surface and atmospheric evolution, and tectonics.
Planetary Evolution can also involve the study of a planet’s history, including events such as impacts, volcanic activity, erosion, and climate changes. It examines how these factors contribute to features like topography, the presence of water, and the development of an atmosphere, as well as the potential for life to exist.
Understanding Planetary Evolution is crucial in astrobiology, comparative planetology, and solar system science, as it helps researchers understand not only our own planet but also the diverse conditions that may exist on other celestial bodies in our solar system and beyond.
