Planetary Defense Frequently Asked Questions (Schema.org FAQ)

How big is 3200 Phaethon (Geminids Parent Body) compared to city landmarks?

3200 Phaethon (Geminids Parent Body) has an estimated diameter between 5100m and 5800m. At its upper-bound size of 5800m, it stands 1309% as tall as the 443m Empire State Building in New York City and 1758% of the 330m Eiffel Tower.

Will 3200 Phaethon (Geminids Parent Body) impact Earth during its 2026-10-30 approach?

No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 3200 Phaethon (Geminids Parent Body) will pass safely at a minimum distance of 7.54 Lunar Distances (2,898,376 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
