469219 Kamo`oalewa (2016 HO3)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 469219 Kamo`oalewa (2016 HO3) is a Unreported by NASA NeoWs body measuring between 36.52m and 81.67m in diameter. On 2026-11-05, it completes a cislunar approach at 44.83 Lunar Distances (17,240,443.4 km) with a relative heliocentric velocity of 4.60 km/s.
469219 Kamo`oalewa (2016 HO3) (JPL ID 2469219) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 36.5m–81.7m (mean 59.1m). On 2026-11-05, it transits Earth's cislunar surveillance sector at 44.830 Lunar Distances (17,240,443 km) with a relative velocity of 4.60 km/s and a theoretical kinetic energy reserve of 0.78 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
