The Tunguska event in 1908 Siberia is supposed to have been the result
of an asteroid or comet less than 100m across... That would have been
a real mess in a populated area! I don't know for sure, but I'd guess
that there are more smaller asteroids than big ones. And while there
is no historical evidence of an asteroid killing a human being, there
is at least one incident of a car being hit. The smaller ones are
harder to find, and once all the large ones are mapped, I hope we
continue to look for smaller and smaller asteroids and comets.
