138852 (2000 WN10)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 138852 (2000 WN10) is a Unreported by NASA NeoWs body measuring between 232.57m and 520.04m in diameter. On 2026-11-11, it completes a cislunar approach at 71.50 Lunar Distances (27,496,685.1 km) with a relative heliocentric velocity of 16.46 km/s.
138852 (2000 WN10) (JPL ID 2138852) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 232.6m–520.0m (mean 376.3m). On 2026-11-11, it transits Earth's cislunar surveillance sector at 71.500 Lunar Distances (27,496,685 km) with a relative velocity of 16.46 km/s and a theoretical kinetic energy reserve of 2575.39 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
