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.
All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday.

Here's one less thing to worry about—or to look forward to: NASA has ruled out any chance that an asteroid called 2024 YR4 will hit the moon in 2032. Last year, the uncertainty surrounding the space rock's orbital path held ...
