(2002 TA69)

Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2002 TA69) is a S-type (Silicate Stony) body measuring between 520.66m and 1164.23m in diameter. On 2026-10-26, it completes a cislunar approach at 34.79 Lunar Distances (13,378,772.8 km) with a relative heliocentric velocity of 23.12 km/s.

LOCAL SERVER-BOX GEMMA SYNTHESIS (http://127.0.0.1:11434/v1):

(2002 TA69) (JPL ID 3137852) is a S-type (Silicate Stony) Near-Earth Asteroid spanning 520.7m–1164.2m (mean 842.4m). On 2026-10-26, it transits Earth's cislunar surveillance sector at 34.789 Lunar Distances (13,378,773 km) with a relative velocity of 23.12 km/s and a theoretical kinetic energy reserve of 56964.23 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 (2002 TA69) compared to city landmarks?

(2002 TA69) has an estimated diameter between 520.66m and 1164.23m. At its upper-bound size of 1164.23m, it stands 263% as tall as the 443m Empire State Building in New York City and 353% of the 330m Eiffel Tower.

Will (2002 TA69) impact Earth during its 2026-10-26 approach?

No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2002 TA69) will pass safely at a minimum distance of 34.79 Lunar Distances (13,378,772.8 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
