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 first few billion years of Earth's history saw the rise of life, the atmosphere and the oceans. Still, that time is shrouded in mystery: Not many rocks remain that preserve a record of those early iterations of our modern ...

The long, puzzling dwarf planet Ceres, in reality the first named asteroid, has surface features that are much more complex than previously thought. Or at least that's the conclusion of a recent paper presented at the European ...

Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal ...

China's Tianwen-2 sample-return mission is well on its way to its target, an asteroid called Kamo'oalewa. The spacecraft left Earth in May 2025 and should return in late 2027 with samples of a space rock that scientists had ...
Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility. But in practice, ...

Earth has a group of cosmic stalkers. Known as "co-orbitals," these small bits of rock have a 1:1 mean motion resonance with Earth. Basically, they take the exact same amount of time to orbit the sun as we do. Astronomers ...
