Asteroid 363790 (2005 JE46)
Closest pass on 2026-Nov-13 19:58 TDB (Julian Date: 2461358.332236681)
Key Facts
- On 2026-Nov-13 19:58, asteroid 363790 (2005 JE46) passed Earth at a nominal distance of 7,700,000 km (20 lunar distances).
- At closest approach, the object was traveling at 14.7 km/s relative to Earth.
- The object has an estimated size of 956 m, which is just over 9 football pitches.
- The miss distance was just over 20 times the distance to the Moon.
- Hazard classification: 140 to 1,000 meters. Causes widespread continental destruction, severe climatic cooling from injected dust, and potentially lethal ocean tsunamis if hitting water; Congress designated 140 meters as the threshold for mandatory congressional NEO tracking.
