Asteroid (2019 WT1)
Closest pass on 2026-Nov-18 22:02 TDB (Julian Date: 2461363.418058479)
Key Facts
- On 2026-Nov-18 22:02, asteroid (2019 WT1) passed Earth at a nominal distance of 7,540,000 km (19.6 lunar distances).
- At closest approach, the object was traveling at 9.75 km/s relative to Earth.
- The object has an estimated size of 15.5 m, which is about one and a half school buses.
- The miss distance was about 20 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.
