(2011 SR69)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2011 SR69) is a Unreported by NASA NeoWs body measuring between 253.84m and 567.6m in diameter. On 2026-11-02, it completes a cislunar approach at 134.47 Lunar Distances (51,714,950.9 km) with a relative heliocentric velocity of 14.35 km/s.
(2011 SR69) (JPL ID 3579081) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 253.8m–567.6m (mean 410.7m). On 2026-11-02, it transits Earth's cislunar surveillance sector at 134.475 Lunar Distances (51,714,951 km) with a relative velocity of 14.35 km/s and a theoretical kinetic energy reserve of 2542.48 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.
