Just some numbers for those who think about diverting the asteroid by pumping energy into it.
Assumptions:
- $60$ km diameter, same as https://en.wikipedia.org/wiki/Chicxulub_impactor
- $113097 km^3$ volume
- $2g/cm^3$ density,
- $2.262*10^{17}kg$ source,
- If we impart an impulse in 3 months(ie. 9 months before impact) we need a delta-v of $0.27m/s$.
- This will take $2.944*10^{8}TJ$.
- Or about 75 times the total energy yield of all nuclear bombs detonated to date.
- This does not include the energy needed to get a bomb to the asteroid.
