Asteroid 612856 (2004 TP1)
Closest pass on 2026-Nov-01 02:13 TDB (Julian Date: 2461345.592488308)
Key Facts
- On 2026-Nov-01 02:13, asteroid 612856 (2004 TP1) passed Earth at a nominal distance of 9,300,000 km (24.2 lunar distances).
- At closest approach, the object was traveling at 12.7 km/s relative to Earth.
- The object has an estimated size of 251 m, which is 0.762 times the size of a Eiffel Tower.
- The miss distance was just over 24 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.
