Asteroid 2006 SC was discovered on September 16, 2006 by the Catalina Sky Survey Mission (CSS)
Object is too small (diameter of about 20—60 meters) to result in heavy damage on the ground (absolute magnitude > 25)

Number of original observations: 108
Arc : 2006 09 16 - 2006 10 13
Nominal rms: 0″.72 (209 residuals)

Possible collisions in: 2053





Year: 2053

Impact date: 2053 09 13.608 (UT)   Vimpact= 16.321 km/sec   Ψimpact = 19°.01  

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.
