Closest pass on 2026-Sep-28 06:45 TDB (Julian Date: 2461311.781406648)
Key Facts
- On 2026-Sep-28 06:45, asteroid (2026 SA8) passed Earth at a nominal distance of 380,000 km (0.988 lunar distances).
- At closest approach, the object was traveling at 6.61 km/s relative to Earth.
- The object has an estimated size of 6.66 m, which is 0.555 times the size of a school bus.
- The miss distance was about the distance to the Moon.
- Hazard classification: Under 10 meters. Typically burns up harmlessly high in the upper atmosphere, producing a bright meteor fireball with negligible ground risk and occasional small meteorite fragments.
