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 ...

Researchers analyzed 28 Ryugu asteroid samples and found preserved magnetic signals that record early solar system magnetic fields and water-driven alteration on its parent body.

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...
