Lots of people still laugh when there is talk of setting up an asteroid defence system. The chances of a big hit are small but there's always that chance, the planets have swept up most of the rocks flying round the solar system but there will always be rocks out there.

Who would have thought that one of the Planets in our solar system would have experienced multiple hits even during our life times (comet striking Jupiter).

There are lots of smaller, but dangerous meteoroids or comets smacking into the earth frequently. Tunguska in 1908. An event in the Amazon in the 1930s, I forget the details. Some reports blame a fireball for the Chicago fire in 1871 (nearby towns were touched off as well). Biela's Comet

This year Norway was hit by a meteoroid that by some reports may have caused a 20 Kiloton explosion. Imagine if something like that his some populated area.
