Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is 6489 Golevka (1991 JX) compared to city landmarks?
6489 Golevka (1991 JX) has an estimated diameter between 480m and 530m. At its upper-bound size of 530m, it stands 120% as tall as the 443m Empire State Building in New York City and 161% of the 330m Eiffel Tower.
Will 6489 Golevka (1991 JX) impact Earth during its 2026-10-29 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 6489 Golevka (1991 JX) will pass safely at a minimum distance of 12.10 Lunar Distances (4,651,240 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
