Scientists are astounded by the discovery of an asteroid that spins faster than any previously recorded. Named 2025 MN45, this asteroid completes a full rotation in just 112 seconds, shattering the record for asteroids larger than 500 meters. The Vera C. Rubin Observatory in Chile, which made the discovery, is designed to map the southern sky and monitor celestial objects, including asteroids and comets. The rapid spin of 2025 MN45 suggests it has a solid, dense structure, challenging the traditional view of asteroids as 'rubble piles'. This finding could reshape our understanding of the asteroid belt and the early history of our solar system, offering valuable insights into the composition and formation of these objects.
