World's Biggest Camera Spots Fastest-Spinning Giant Asteroid, Rewriting Theories

• The Rubin Observatory's new digital camera, the largest ever built, has identified an unusually fast-spinning asteroid.
• Among thousands of new asteroid discoveries, 19 were found rotating far faster than expected, challenging existing theories.
• One object, 2025 MN45, measuring 710 meters across, spins every 1.88 minutes, suggesting it's solid rock, not a rubble pile.
• This discovery, led by astronomer Sarah Greenstreet, provides fresh clues about asteroid strength, origins, and internal makeup.
• The findings from the Chilean observatory are expected to reshape asteroid science and deepen understanding of Solar System history.

Why It Matters: The Rubin Observatory's new camera found a giant, rapidly spinning asteroid, challenging existing theories on asteroid composition.
