(2019 UG2)

Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2019 UG2) is a C-type (Carbonaceous Chondrite) body measuring between 36.69m and 82.04m in diameter. On 2026-10-22, it completes a cislunar approach at 85.47 Lunar Distances (32,868,548.3 km) with a relative heliocentric velocity of 12.32 km/s.

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

(2019 UG2) (JPL ID 3879285) is a C-type (Carbonaceous Chondrite) Near-Earth Asteroid spanning 36.7m–82.0m (mean 59.4m). On 2026-10-22, it transits Earth's cislunar surveillance sector at 85.468 Lunar Distances (32,868,548 km) with a relative velocity of 12.32 km/s and a theoretical kinetic energy reserve of 5.68 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 (2019 UG2) compared to city landmarks?

(2019 UG2) has an estimated diameter between 36.69m and 82.04m. At its upper-bound size of 82.04m, it stands 19% as tall as the 443m Empire State Building in New York City and 25% of the 330m Eiffel Tower.

Will (2019 UG2) impact Earth during its 2026-10-22 approach?

No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2019 UG2) will pass safely at a minimum distance of 85.47 Lunar Distances (32,868,548.3 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
