[meteorite-list] Preliminary MOSS meteorite classification

[Larry Lebofsky]

Hi Ed:

That is almost as hard to believe as meteor showers ("debris" from a comet) 
occurring on the same day each year!

Actually, probably does not have to be every year, just every few years. If 
these come from the breakup of a near Earth asteroid, the debris would 
probably spread out from the asteroid in a manner similar to a comet tail.
