(2017 TK6)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2017 TK6) is a S-type (Silicate Stony) body measuring between 31.52m and 70.48m in diameter. On 2026-10-25, it completes a cislunar approach at 47.92 Lunar Distances (18,428,131.2 km) with a relative heliocentric velocity of 15.06 km/s.
(2017 TK6) (JPL ID 3786454) is a S-type (Silicate Stony) Near-Earth Asteroid spanning 31.5m–70.5m (mean 51m). On 2026-10-25, it transits Earth's cislunar surveillance sector at 47.919 Lunar Distances (18,428,131 km) with a relative velocity of 15.06 km/s and a theoretical kinetic energy reserve of 5.37 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 (2017 TK6) compared to city landmarks?
(2017 TK6) has an estimated diameter between 31.52m and 70.48m. At its upper-bound size of 70.48m, it stands 16% as tall as the 443m Empire State Building in New York City and 21% of the 330m Eiffel Tower.
Will (2017 TK6) impact Earth during its 2026-10-25 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2017 TK6) will pass safely at a minimum distance of 47.92 Lunar Distances (18,428,131.2 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
