509505 (2007 VL8)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 509505 (2007 VL8) is a C-type (Carbonaceous Chondrite) body measuring between 150.16m and 335.77m in diameter. On 2026-10-18, it completes a cislunar approach at 50.46 Lunar Distances (19,404,413.4 km) with a relative heliocentric velocity of 9.78 km/s.
509505 (2007 VL8) (JPL ID 2509505) is a C-type (Carbonaceous Chondrite) Near-Earth Asteroid spanning 150.2m–335.8m (mean 243m). On 2026-10-18, it transits Earth's cislunar surveillance sector at 50.457 Lunar Distances (19,404,413 km) with a relative velocity of 9.78 km/s and a theoretical kinetic energy reserve of 244.70 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 509505 (2007 VL8) compared to city landmarks?
509505 (2007 VL8) has an estimated diameter between 150.16m and 335.77m. At its upper-bound size of 335.77m, it stands 76% as tall as the 443m Empire State Building in New York City and 102% of the 330m Eiffel Tower.
Will 509505 (2007 VL8) impact Earth during its 2026-10-18 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 509505 (2007 VL8) will pass safely at a minimum distance of 50.46 Lunar Distances (19,404,413.4 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
