(2013 AH53)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2013 AH53) is a Q-type (Olivine-Pyroxene) body measuring between 19.26m and 43.06m in diameter. On 2026-10-18, it completes a cislunar approach at 71.47 Lunar Distances (27,484,782.2 km) with a relative heliocentric velocity of 9.14 km/s.
(2013 AH53) (JPL ID 3623684) is a Q-type (Olivine-Pyroxene) Near-Earth Asteroid spanning 19.3m–43.1m (mean 31.2m). On 2026-10-18, it transits Earth's cislunar surveillance sector at 71.469 Lunar Distances (27,484,782 km) with a relative velocity of 9.14 km/s and a theoretical kinetic energy reserve of 0.45 megatons TNT. Its well-constrained heliocentric ephemeris passes safely outside Earth capture corridors while serving as an orbital calibration target.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2013 AH53) compared to city landmarks?
(2013 AH53) has an estimated diameter between 19.26m and 43.06m. At its upper-bound size of 43.06m, it stands 10% as tall as the 443m Empire State Building in New York City and 13% of the 330m Eiffel Tower.
Will (2013 AH53) impact Earth during its 2026-10-18 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2013 AH53) will pass safely at a minimum distance of 71.47 Lunar Distances (27,484,782.2 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
