Impact date: 2088 06 22.202 (UT)   Vimpact= 12.818 km/sec   Ψimpact = 5°.63  

dev/σ
Deviation from the nominal orbit parameter divided by the respective uncertainty.
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.
