Steve (and list),
True, but I meant a meteorite whose composition was from entirely outside our
solar system. To borrow a term from Duncan Steel, a truely "rogue asteroid."
How could we identify it as such (e.g., new "strange" composition of minerals,
different isotopes, "new" elements or compounds - or would it just be a
"ordinary" chondrite from another solar system - the possibilities are
astounding and extremely challenging!).
