85585 Mjolnir (1998 FG2)

Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 85585 Mjolnir (1998 FG2) is a Not published by JPL SBDB body measuring between 126.1m and 281.9m in diameter. On 2032-03-01, it completes a cislunar approach at 16.52 Lunar Distances (6,352,101 km) with a relative heliocentric velocity of 8.13 km/s.

AI-ASSISTED SUMMARY (may contain errors):

85585 Mjolnir (1998 FG2) (JPL ID 85585) is a Not published by JPL SBDB Near-Earth Asteroid spanning 126.1m–281.9m (mean 204m). On 2032-03-01, it transits Earth's cislunar surveillance sector at 16.525 Lunar Distances (6,352,101 km) with a relative velocity of 8.13 km/s and a theoretical kinetic energy reserve of 100.07 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.
