(2014 JS57)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2014 JS57) is a Unreported by NASA NeoWs body measuring between 89.24m and 199.54m in diameter. On 2026-10-28, it completes a cislunar approach at 170.50 Lunar Distances (65,569,040.7 km) with a relative heliocentric velocity of 11.22 km/s.
(2014 JS57) (JPL ID 3671134) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 89.2m–199.5m (mean 144.4m). On 2026-10-28, it transits Earth's cislunar surveillance sector at 170.499 Lunar Distances (65,569,041 km) with a relative velocity of 11.22 km/s and a theoretical kinetic energy reserve of 67.61 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
