Recommendations We have decided to put the chances that earth is going to be hit by a life-threatening impact object into a data table. (#) 1 megatonne of TNT= 1,000,000 tonnes of high explosives (the atomic bomb droppes on Hiroshima was equal to 13,000 tonnes of TNT or 0.013 megatonnes)
 * Asteroid Diameter (km) || Estimated Number of NEO's* || Impact Probability (once per number of years) || Impact Energy (Megatonnes of TNT#) || Crater Size (km) ||
 * 0.001 (1 metre) || 10,000,000 || 100 || 0.1 || 0.01 (10m) ||
 * 0.1 (100m) || 100,000 || 10,000 || 10 || 1 ||
 * 1 || 1,000 || 100,000 || 10,000 || 10 ||
 * 10 || 10 || 1,000,000 || 1000000 || 100 ||
 * NEO=Near Earth Object (Asteroid or Comet)
