Discovery 5 months, 2 weeks agoAstronomers Using The NSF–DOE Rubin Discovered Asteroid 2025 MN45 In The Main Asteroid Belt. ~710m Wide, It Spins Once Every 1.88 Mins—The Fastest Ever Recorded For An Asteroid Over 500m. Unlike Typical Rubble-Pile Asteroids, Its Solid, Dense Rock Lets It Exceed The Usual Spin Limit, Revealing Clues About Asteroid Structure & Evolution.
NSF–DOE Vera C. Rubin Observatory Spots Record-Breaking Asteroid in Pre-Survey Observations | Rubin ObservatoryAstronomers analyzing data from NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy’s Office of Science, have discovered the fastest-ever spinning asteroid with a diameter over half a kilometer — a feat uniquely enabled by Rubin. The study provides crucial information about asteroid composition and evolution, and demonstrates how Rubin is pushing the boundaries of what we can discover within our own Solar System.
