(2015 KU121)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2015 KU121) is a Unreported by NASA NeoWs body measuring between 69.91m and 156.33m in diameter. On 2026-11-03, it completes a cislunar approach at 167.65 Lunar Distances (64,474,218.5 km) with a relative heliocentric velocity of 18.05 km/s.
(2015 KU121) (JPL ID 3720359) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 69.9m–156.3m (mean 113.1m). On 2026-11-03, it transits Earth's cislunar surveillance sector at 167.653 Lunar Distances (64,474,219 km) with a relative velocity of 18.05 km/s and a theoretical kinetic energy reserve of 84.10 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
