Asteroid (2026 FC6)
Closest pass on 2026-Sep-29 02:35 TDB (Julian Date: 2461312.607306926)
Key Facts
- On 2026-Sep-29 02:35, asteroid (2026 FC6) passed Earth at a nominal distance of 10,800,000 km (28.1 lunar distances).
- At closest approach, the object was traveling at 26.1 km/s relative to Earth.
- The object has an estimated size of 128 m, which is about 11 school buses.
- The miss distance was just over 28 times the distance to the Moon.
- Hazard classification: 50 to 140 meters. Reaches Earth surface to carve a crater over a kilometer wide (like Meteor Crater, Arizona), destroying infrastructure across an entire metropolitan region and generating damaging regional seismic waves.
