Close Approach Record

Asteroid (2001 KF54)

Closest pass on 2026-Nov-06 03:38 TDB (Julian Date: 2461350.65164014)

Key Facts

  • On 2026-Nov-06 03:38, asteroid (2001 KF54) passed Earth at a nominal distance of 7,240,000 km (18.8 lunar distances).
  • At closest approach, the object was traveling at 16.4 km/s relative to Earth.
  • The object has an estimated size of 391 m, which is about one and a half Eiffel Towers.
  • The miss distance was just under 19 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.
