Asteroid 2005 QK76 was discovered on August 30, 2005 with the Spacewatch 0.9m telescope at Kitt Peak.
Object is too small (diameter: 20—60) to result in heavy damage on the ground (absolute magnitude > 25).

Number of original observations: 14
Arc : 2005 08 30 - 2005 08 31
Nominal rms: 0″.58 (28 residuals)

Possible collisions in: 2030





Year: 2030

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.
