Impact date: 2050 12 21.909 (UT)   Vimpact= 24.390 km/sec   Ψimpact = 57°.30  

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.
