(2017 SF14)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2017 SF14) is a Unreported by NASA NeoWs body measuring between 34.08m and 76.21m in diameter. On 2026-10-29, it completes a cislunar approach at 165.42 Lunar Distances (63,615,115.8 km) with a relative heliocentric velocity of 16.07 km/s.
(2017 SF14) (JPL ID 3781867) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 34.1m–76.2m (mean 55.1m). On 2026-10-29, it transits Earth's cislunar surveillance sector at 165.419 Lunar Distances (63,615,116 km) with a relative velocity of 16.07 km/s and a theoretical kinetic energy reserve of 7.71 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
