(2018 DA2)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2018 DA2) is a X-type (Enstatite-Metallic) body measuring between 58.69m and 131.23m in diameter. On 2026-10-25, it completes a cislunar approach at 153.13 Lunar Distances (58,890,104.1 km) with a relative heliocentric velocity of 14.73 km/s.
(2018 DA2) (JPL ID 3799748) is a X-type (Enstatite-Metallic) Near-Earth Asteroid spanning 58.7m–131.2m (mean 95m). On 2026-10-25, it transits Earth's cislunar surveillance sector at 153.132 Lunar Distances (58,890,104 km) with a relative velocity of 14.73 km/s and a theoretical kinetic energy reserve of 33.16 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 (2018 DA2) compared to city landmarks?
(2018 DA2) has an estimated diameter between 58.69m and 131.23m. At its upper-bound size of 131.23m, it stands 30% as tall as the 443m Empire State Building in New York City and 40% of the 330m Eiffel Tower.
Will (2018 DA2) impact Earth during its 2026-10-25 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2018 DA2) will pass safely at a minimum distance of 153.13 Lunar Distances (58,890,104.1 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
