(2009 UY17)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2009 UY17) is a V-type (Basaltic Achondrite) body measuring between 174m and 389.08m in diameter. On 2026-10-19, it completes a cislunar approach at 68.13 Lunar Distances (26,198,830.9 km) with a relative heliocentric velocity of 23.62 km/s.
(2009 UY17) (JPL ID 3472299) is a V-type (Basaltic Achondrite) Near-Earth Asteroid spanning 174.0m–389.1m (mean 281.5m). On 2026-10-19, it transits Earth's cislunar surveillance sector at 68.125 Lunar Distances (26,198,831 km) with a relative velocity of 23.62 km/s and a theoretical kinetic energy reserve of 2218.93 megatons TNT. Classified as a Potentially Hazardous Asteroid (PHA) due to its Minimum Orbit Intersection Distance (MOID <= 0.05 AU) and absolute magnitude (H <= 22.0), it remains under high-priority radar and optical astrometric tracking.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2009 UY17) compared to city landmarks?
(2009 UY17) has an estimated diameter between 174m and 389.08m. At its upper-bound size of 389.08m, it stands 88% as tall as the 443m Empire State Building in New York City and 118% of the 330m Eiffel Tower.
Will (2009 UY17) impact Earth during its 2026-10-19 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2009 UY17) will pass safely at a minimum distance of 68.13 Lunar Distances (26,198,830.9 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
