Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is 6178 (1986 DA) Metallic PGM Core compared to city landmarks?
6178 (1986 DA) Metallic PGM Core has an estimated diameter between 2100m and 2300m. At its upper-bound size of 2300m, it stands 519% as tall as the 443m Empire State Building in New York City and 697% of the 330m Eiffel Tower.
Will 6178 (1986 DA) Metallic PGM Core impact Earth during its 2026-10-25 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 6178 (1986 DA) Metallic PGM Core will pass safely at a minimum distance of 21.40 Lunar Distances (8,226,160 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
