A team of researchers from Hokkaido University and several other institutions in Japan found that particles of magnetite in asteroid Ryugu are devoid of magnetism, likely due to high-velocity micrometeoroid collisions altering the magnetite's chemical structure.
Understanding space weathering due to micrometeoroids and solar wind on asteroids like Ryugu can provide insights into the evolution of asteroids and the Solar System, highlighting the challenges of studying asteroids solely through meteorites.
