(2015 LJ)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2015 LJ) is a Unreported by NASA NeoWs body measuring between 30.52m and 68.24m in diameter. On 2026-11-01, it completes a cislunar approach at 118.77 Lunar Distances (45,673,390.5 km) with a relative heliocentric velocity of 4.62 km/s.
(2015 LJ) (JPL ID 3720918) is a Unreported by NASA NeoWs Near-Earth Asteroid spanning 30.5m–68.2m (mean 49.4m). On 2026-11-01, it transits Earth's cislunar surveillance sector at 118.765 Lunar Distances (45,673,391 km) with a relative velocity of 4.62 km/s and a theoretical kinetic energy reserve of 0.46 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 LJ) compared to city landmarks?
(2015 LJ) has an estimated diameter between 30.52m and 68.24m. At its upper-bound size of 68.24m, it stands 15% as tall as the 443m Empire State Building in New York City and 21% of the 330m Eiffel Tower.
What does the stored 2026-11-01 close-approach estimate show?
This catalog snapshot lists a nominal miss distance of 118.77 Lunar Distances (45,673,390.5 km) for (2015 LJ). This is not an impact prediction; check the latest NASA JPL record for updated orbital estimates. The 3D impact simulation is hypothetical.
