(2003 RL10)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2003 RL10) is a Unreported by NASA NeoWs body measuring between 322.52m and 721.17m in diameter. On 2026-10-28, it completes a cislunar approach at 87.97 Lunar Distances (33,830,447.2 km) with a relative heliocentric velocity of 14.54 km/s.
(2003 RL10) (JPL ID 3159894) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 322.5m–721.2m (mean 521.8m). On 2026-10-28, it transits Earth's cislunar surveillance sector at 87.969 Lunar Distances (33,830,447 km) with a relative velocity of 14.54 km/s and a theoretical kinetic energy reserve of 5354.06 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
