Tiny grains from the asteroid Ryugu have shed light on the origins of the outer solar system over 4.6 billion years ago. MIT researchers analyzed precious samples from the asteroid Ryugu ...

Harvard astronomer Avi Loeb suggests that if interstellar object 3I/ATLAS isn't a comet, nor an asteroid, it may have been ...

Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed ...

Our solar system is estimated to be about 4.57 billion years old. Previous analyses of ancient meteorites have shown that minerals were created through chemical reactions with water as far back as ...

Initial analysis of the samples from asteroid Ryugu show the rock could change our understanding of the early solar system. Hayabusa2's Ancient Asteroid Samples Are the Most Pristine Ever Seen ...

The near-Earth asteroid Ryugu formed far from the sun, in the cold depths of the outer solar system, according to new analysis of samples returned from Ryugu by the Japanese Hayabusa2 mission.

Ancient asteroid samples contain crucial clues about the solar system, a new study has revealed. The study, published in Nature Astronomy, presents findings from Japanese Hayabusa2, a mission ...

A new SPHERE/VLT image of Hygiea, which could be the Solar System’s smallest dwarf planet yet. As an object in the main asteroid belt, Hygiea satisfies right away three of the four requirements ...

To date, astronomers haven't seen asteroid families (that is, asteroids with a common source) in the Solar System older than about 3 billion years -- well after the star system came to be 4.5 ...

And now a third moon has been found, making Elektra a quadruple asteroid system. This one measures just 1.6 km (1 mile) wide, orbiting the main body every 16 hours at a distance of 344 km (214 miles).

Our solar system has never received any visitors that we’ve been able to detect — until now. About a month ago, astronomers noticed a fast-moving, rocky asteroid hurtling through our solar system.
