Asteroids as a research area encompasses the scientific investigation of small rocky bodies primarily located in the asteroid belt and throughout the Solar System, focusing on their composition, internal structure, dynamical evolution, and role in planetary formation and collisional processes. This field integrates observational astronomy, spectroscopy, celestial mechanics, planetary geology, and space mission data to constrain asteroid taxonomies, surface and subsurface properties, impact hazards, and resource potential. Research addresses accretion and differentiation histories, space weathering, binary and rubble-pile formation, migration mechanisms, and their contribution to the delivery of volatiles and organics to terrestrial planets, providing constraints on early Solar System conditions.
A huge asteroid that was briefly feared to strike Earth now has a nearly 4% chance of smashing into the moon, according to new data from the James Webb Space Telescope.
