2024 YR4
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), 2024 YR4 is a S-type (Silicate Stony) body measuring between 40m and 90m in diameter. On 2032-12-22, it completes a cislunar approach at 0.68 Lunar Distances (261,392 km) with a relative heliocentric velocity of 17.32 km/s.
2024 YR4 (JPL ID 2024-YR4) is a S-type (Silicate Stony) Near-Earth Asteroid spanning 40.0m–90.0m (mean 65m). On 2032-12-22, it transits Earth's cislunar surveillance sector at 0.680 Lunar Distances (261,392 km) with a relative velocity of 17.32 km/s and a theoretical kinetic energy reserve of 14.69 megatons TNT. Classified as a Potentially Hazardous Asteroid (PHA) due to its Minimum Orbit Intersection Distance (MOID <= 0.05 AU) and absolute magnitude (H <= 22.0), it remains under high-priority radar and optical astrometric tracking.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is 2024 YR4 compared to city landmarks?
2024 YR4 has an estimated diameter between 40m and 90m. At its upper-bound size of 90m, it stands 20% as tall as the 443m Empire State Building in New York City and 27% of the 330m Eiffel Tower.
Will 2024 YR4 impact Earth during its 2032-12-22 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm 2024 YR4 will pass safely at a minimum distance of 0.68 Lunar Distances (261,392 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
