Should it perchance strike our planet with the force of “141 gigatons of TNT,” the destruction would be considerable. If a city were directly hit, the resulting crater would be “11 miles wide.” The human casualty count could be as high as 13 million, two million of which would be subject to instant vaporization.
The statistical chances of this occurring are one in thousands, which sounds lucky unless Earth happens to be that one. If such a strike were to occur, then even the Super Bowl would be second-rate news.
