(2017 UX7)
Tracked by NASA JPL Near-Earth Object Web Service (NeoWs), (2017 UX7) is a M-type (Metallic Nickel-Iron) body measuring between 20.16m and 45.09m in diameter. On 2026-10-22, it completes a cislunar approach at 16.90 Lunar Distances (6,500,634.2 km) with a relative heliocentric velocity of 10.33 km/s.
(2017 UX7 transits the cislunar surveillance corridor at 16.90 Lunar Distances (6,497,898 km) with a relative heliocentric velocity of 10.33 km/s among 48 tracked Near-Earth Objects (4 PHAs). Under classical kinetic scaling (E = 0.5 * m * v^2) and Collins-Melosh-Marcus impact laws, its 165.0m mass carries 89.98 MT TNT equivalent energy—corresponding to a theoretical 2554m final crater and 20.84 km 5-psi overpressure radius while remaining safely on a non-intersecting hyperbolic trajectory.

Planetary Defense Frequently Asked Questions (Schema.org FAQ)
How big is (2017 UX7) compared to city landmarks?
(2017 UX7) has an estimated diameter between 20.16m and 45.09m. At its upper-bound size of 45.09m, it stands 10% as tall as the 443m Empire State Building in New York City and 14% of the 330m Eiffel Tower.
Will (2017 UX7) impact Earth during its 2026-10-22 approach?
No. NASA JPL Center for Near-Earth Object Studies (CNEOS) orbital solutions confirm (2017 UX7) will pass safely at a minimum distance of 16.90 Lunar Distances (6,500,634.2 km). You can still simulate a hypothetical street-level impact in our 3D CesiumJS simulator.
