(2017 UL44)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2017 UL44) is a Unreported by NASA NeoWs body measuring between 46.19m and 103.29m in diameter. On 2026-10-29, it completes a cislunar approach at 90.60 Lunar Distances (34,840,714.5 km) with a relative heliocentric velocity of 14.14 km/s.
(2017 UL44) (JPL ID 3788165) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 46.2m–103.3m (mean 74.7m). On 2026-10-29, it transits Earth's cislunar surveillance sector at 90.596 Lunar Distances (34,840,715 km) with a relative velocity of 14.14 km/s and a theoretical kinetic energy reserve of 14.86 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
