Asteroid 2009 VA was discovered on October 6, 2009 by the Catalina Sky Survey about 15 hours before closest approach to the Earth when it passed about 20000 kilometers from the planet (well inside the orbits of geosynchronous satellites). This object has a diameter less than 10 meters.

Impact date: 2025 11 06.843 (UT)   Vimpact= 13.948 km/sec   Ψimpact = 22°.22  

Vimpact
The velocity of the asteroid relative to the Earth at the moment of impact.
Ψimpact
The impact angle is measured from the vertical axis that goes through the impact point. Thus, the impact angle is 0 degrees for a vertical impact.
rms
Root mean square for the derived impact orbit.
