(2016 LN1)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2016 LN1) is a S-type (Silicate Stony) body measuring between 280.9m and 628.12m in diameter. On 2026-10-21, it completes a cislunar approach at 78.78 Lunar Distances (30,294,985.2 km) with a relative heliocentric velocity of 14.12 km/s.
(2016 LN1) (JPL ID 3753695) is a S-type (Silicate Stony) Near-Earth Asteroid spanning 280.9m–628.1m (mean 454.5m). On 2026-10-21, it transits Earth's cislunar surveillance sector at 78.776 Lunar Distances (30,294,985 km) with a relative velocity of 14.12 km/s and a theoretical kinetic energy reserve of 3335.69 megatons TNT. Classified as a Potentially Hazardous Asteroid (PHA) due to its Minimum Orbit Intersection Distance (MOID <= 0.05 AU) and absolute magnitude (H <= 22.0), it remains under high-priority radar and optical astrometric tracking.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2016 LN1) compared to city landmarks?
(2016 LN1) has an estimated diameter between 280.9m and 628.12m. At its upper-bound size of 628.12m, it stands 142% as tall as the 443m Empire State Building in New York City and 190% of the 330m Eiffel Tower.
Will (2016 LN1) impact Earth during its 2026-10-21 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2016 LN1) will pass safely at a minimum distance of 78.78 Lunar Distances (30,294,985.2 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
