Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2005 GU) is a Unreported by NASA NeoWs body measuring between 262.15m and 586.19m in diameter. On 2026-11-02, it completes a cislunar approach at 64.25 Lunar Distances (24,708,416.6 km) with a relative heliocentric velocity of 27.17 km/s.

AI-ASSISTED SUMMARY (may contain errors):

(2005 GU) (JPL ID 3275512) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 262.1m–586.2m (mean 424.2m). On 2026-11-02, it transits Earth's cislunar surveillance sector at 64.249 Lunar Distances (24,708,417 km) with a relative velocity of 27.17 km/s and a theoretical kinetic energy reserve of 10045.82 megatons TNT. Classified as a Potentially Hazardous Asteroid (PHA) due to its Minimum Orbit Intersection Distance (MOID <= 0.05 AU) and absolute magnitude (H <= 22.0), it remains under high-priority radar and optical astrometric tracking.
