Asteroid (2017 UX7)
Closest pass on 2026-Oct-22 17:08 TDB (Julian Date: 2461336.213946669)
Key Facts
- On 2026-Oct-22 17:08, asteroid (2017 UX7) passed Earth at a nominal distance of 6,500,000 km (16.9 lunar distances).
- At closest approach, the object was traveling at 10.3 km/s relative to Earth.
- The object has an estimated size of 26.9 m, which is about 2.5 school buses.
- The miss distance was just under 17 times the distance to the Moon.
- Hazard classification: 25 to 50 meters. Can produce a low-altitude airburst or surface crater capable of flattening forests over hundreds of square kilometers and devastating a metropolitan area, comparable to the 1908 Tunguska event.
