| #4 "...Earth's orbital speed averages 29.78 km/s (107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes..." So altering the asteroid's orbital speed by 33 minutes would turn a hit into a miss. |

| #3 Ah, 33 minutes of time, not angle. |

| #2 What is it going to bump into now? Most likely nothing as it was a small body orbiting a larger asteroid. We had plotted its orbit pretty closely so any change would be measurable. This was a successful proof of concept. Given enough warning time, we can deflect an asteroid heading towards Earth. Some 2-3 years warning would be needed at the minimum. |
