Asteroid 2025 MN45 sets new spinning speed record captured by the world’s largest camera at the Rubin Observatory

The Vera C. Rubin Observatory has identified asteroid 2025 MN45, a 710-meter object spinning at an unprecedented rate of once every 1.88 minutes. This discovery challenges existing models of asteroid structure, suggesting a cohesive strength previously thought impossible for such large, fast-rotating bodies. The finding offers new insights into solar system history and asteroid material properties.
