Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials ...

Paleomagnetic analysis of 28 Ryugu asteroid particles reveals stable magnetization acquired within millions of years of solar ...

Active small bodies—including comets, active asteroids, icy minor planets, and transitional objects—occupy a unique position in planetary science. As ...

The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in this ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

Planetary scientists have recently drawn a connection between the birth of Jupiter and the formation zone of Earth, suggesting a shared origin in the early solar system. This revelation not only ...

Small bodies in the solar system have preserved information from different eras of the evolution of our solar system, from the composition of the presolar nebula that is preserved in cometary nuclei ...

The discovery of comet C/2025 V1 (Borisov) has sparked intense global interest among astronomers and space enthusiasts. Found in early November 2025, the comet’s peculiar orbit and chemical makeup ...
