(2015 WZ12)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2015 WZ12) is a Unreported by NASA NeoWs body measuring between 14.61m and 32.66m in diameter. On 2026-10-30, it completes a cislunar approach at 26.70 Lunar Distances (10,266,781.6 km) with a relative heliocentric velocity of 10.34 km/s.
(2015 WZ12) (JPL ID 3735598) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 14.6m–32.7m (mean 23.6m). On 2026-10-30, it transits Earth's cislunar surveillance sector at 26.697 Lunar Distances (10,266,782 km) with a relative velocity of 10.34 km/s and a theoretical kinetic energy reserve of 0.25 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 (2015 WZ12) compared to city landmarks?
(2015 WZ12) has an estimated diameter between 14.61m and 32.66m. At its upper-bound size of 32.66m, it stands 7% as tall as the 443m Empire State Building in New York City and 10% of the 330m Eiffel Tower.
What does the stored 2026-10-30 close-approach estimate show?
This catalog snapshot lists a nominal miss distance of 26.70 Lunar Distances (10,266,781.6 km) for (2015 WZ12). This is not an impact prediction; check the latest NASA JPL record for updated orbital estimates. The 3D impact simulation is hypothetical.
