Gaia mission reveals causes of tumbling asteroids

Scientists using data from the European Space Agency's Gaia mission have explained why some asteroids tumble chaotically while others spin steadily, linking it to collision frequency. The findings, presented at the EPSC-DPS2025 Joint Meeting in Helsinki, show a gap in rotation speeds that divides asteroid populations and indicates most are loose rubble piles. This could improve strategies for deflecting hazardous asteroids.
