Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is 433 Eros (Aten-Amor Crossover) compared to city landmarks?
433 Eros (Aten-Amor Crossover) has an estimated diameter between 340m and 430m. At its upper-bound size of 430m, it stands 97% as tall as the 443m Empire State Building in New York City and 130% of the 330m Eiffel Tower.
Will 433 Eros (Aten-Amor Crossover) impact Earth during its 2026-10-23 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 433 Eros (Aten-Amor Crossover) will pass safely at a minimum distance of 6.12 Lunar Distances (2,352,528 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
