Asteroid (2026 SC)
Closest pass on 2026-Sep-25 13:47 TDB (Julian Date: 2461309.074549382)
Key Facts
- On 2026-Sep-25 13:47, asteroid (2026 SC) passed Earth at a nominal distance of 655,000 km (1.7 lunar distances).
- At closest approach, the object was traveling at 7.75 km/s relative to Earth.
- The object has an estimated size of 18.5 m, which is about one and a half school buses.
- The miss distance was about 1.5 times the distance to the Moon.
- Hazard classification: 10 to 25 meters. Produces a powerful high-altitude shockwave capable of shattering windows, damaging roofs, and producing minor local injuries like the 2013 Chelyabinsk event.
