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.
The chance that a football field-sized asteroid capable of destroying a city will strike Earth in 2032 has fallen to 0.001 percent, the European Space Agency said on Tuesday.

In December 2024, astronomers in Chile spotted a new asteroid streaking through the sky, which they named 2024 YR4. What's significant about this 100m-wide space rock is that it has a small chance of hitting Earth in 2032.
