Nobody has ever had enough bombs to blow up the earth! The figure that there are enough nuclear weapons to kill everybody on the earth 10, 20, 50, or however many times over is an entirely different issue (and is very speculative). It may have been true in the middle 1980s at the peak of the arms race, but since START was signed total number of weapons have fallen continuously.

Earth has a gravitational binding energy of about 2.5* 10^32 Joules. This is the absolute minimum amount of energy needed to destroy the planet. While the Hiroshima bomb release about 6.7*10^13 Joules. So it would take at least 3.7*10^18 or about 3.7 quintillion Hiroshima bombs to completely destroy the planet.

Cannot be answered as it depends on too many variables:

  • yields
  • burst height/depth
  • your definition of blow up
  • etc.
