A lump of space rock the size of a small house will hurtle past Earth on Monday evening in a close encounter that poses no threat to the planet, astronomers said today.
Using our best estimations for the size and speed of the asteroid (much is still unknown about this asteroid), Wolfram|Alpha can calculate what the asteroid impact would be if it did actually make it to Earth (there is virtually no chance that it will). With these numbers, the asteroid would start breaking up 6.6 miles above the Earth’s surface, and then explodes at 3 miles above the surface.
