Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is 65803 Didymos & Dimorphos (DART Target) compared to city landmarks?
65803 Didymos & Dimorphos (DART Target) has an estimated diameter between 740m and 780m. At its upper-bound size of 780m, it stands 176% as tall as the 443m Empire State Building in New York City and 236% of the 330m Eiffel Tower.
Will 65803 Didymos & Dimorphos (DART Target) impact Earth during its 2026-10-25 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 65803 Didymos & Dimorphos (DART Target) will pass safely at a minimum distance of 15.20 Lunar Distances (5,842,880 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
