Well, if the material is cometary, as some researchers are speculating, I wouldn't be too suprised.
As many asteroid chuncks are out there and as many comet chunks are out there, I'd think that a
comet would have had to collide with an asteroid at least once in the past few billion years.  Also,
I wonder about extrasolar material-- surely, in the lifetime of the solar system, we have
intersected through some bits of debris that formed around other stars.  Couldn't some of it be
moving at a relative speed low enough for bits to survive impact?
