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.

Edit:

Other aritcles on wikipedia gives an estimate of 10km as the diameter of the asteroid. This reduces the energy needed to divert it by a factor of 216, meaning we would need the energy of between 3 and 4 Tsar Bombas to divert it.
