488509 (2000 UW13)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 488509 (2000 UW13) is a Q-type (Olivine-Pyroxene) body measuring between 200.7m and 448.79m in diameter. On 2026-10-26, it completes a cislunar approach at 172.73 Lunar Distances (66,425,278.8 km) with a relative heliocentric velocity of 18.63 km/s.
488509 (2000 UW13) (JPL ID 2488509) is a Q-type (Olivine-Pyroxene) Near-Earth Asteroid spanning 200.7m–448.8m (mean 324.7m). On 2026-10-26, it transits Earth's cislunar surveillance sector at 172.726 Lunar Distances (66,425,279 km) with a relative velocity of 18.63 km/s and a theoretical kinetic energy reserve of 2119.05 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 488509 (2000 UW13) compared to city landmarks?
488509 (2000 UW13) has an estimated diameter between 200.7m and 448.79m. At its upper-bound size of 448.79m, it stands 101% as tall as the 443m Empire State Building in New York City and 136% of the 330m Eiffel Tower.
Will 488509 (2000 UW13) impact Earth during its 2026-10-26 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 488509 (2000 UW13) will pass safely at a minimum distance of 172.73 Lunar Distances (66,425,278.8 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
