(2002 GR)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2002 GR) is a V-type (Basaltic Achondrite) body measuring between 60.89m and 136.16m in diameter. On 2026-10-20, it completes a cislunar approach at 113.21 Lunar Distances (43,535,973 km) with a relative heliocentric velocity of 5.85 km/s.
(2002 GR) (JPL ID 3120862) is a V-type (Basaltic Achondrite) Near-Earth Asteroid spanning 60.9m–136.2m (mean 98.5m). On 2026-10-20, it transits Earth's cislunar surveillance sector at 113.207 Lunar Distances (43,535,973 km) with a relative velocity of 5.85 km/s and a theoretical kinetic energy reserve of 5.84 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 GR) compared to city landmarks?
(2002 GR) has an estimated diameter between 60.89m and 136.16m. At its upper-bound size of 136.16m, it stands 31% as tall as the 443m Empire State Building in New York City and 41% of the 330m Eiffel Tower.
Will (2002 GR) impact Earth during its 2026-10-20 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2002 GR) will pass safely at a minimum distance of 113.21 Lunar Distances (43,535,973 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
