(2002 CN15)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2002 CN15) is a X-type (Enstatite-Metallic) body measuring between 183.89m and 411.19m in diameter. On 2026-10-25, it completes a cislunar approach at 57.78 Lunar Distances (22,219,932.4 km) with a relative heliocentric velocity of 26.64 km/s.
(2002 CN15) (JPL ID 3114028) is a X-type (Enstatite-Metallic) Near-Earth Asteroid spanning 183.9m–411.2m (mean 297.5m). On 2026-10-25, it transits Earth's cislunar surveillance sector at 57.779 Lunar Distances (22,219,932 km) with a relative velocity of 26.64 km/s and a theoretical kinetic energy reserve of 3333.61 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 CN15) compared to city landmarks?
(2002 CN15) has an estimated diameter between 183.89m and 411.19m. At its upper-bound size of 411.19m, it stands 93% as tall as the 443m Empire State Building in New York City and 125% of the 330m Eiffel Tower.
Will (2002 CN15) impact Earth during its 2026-10-25 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2002 CN15) will pass safely at a minimum distance of 57.78 Lunar Distances (22,219,932.4 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
