Mystery Meteorite May Not Be From Mercury After All 31
gbrumfiel writes "A strange green meteorite found in Morocco caused a stir in the press earlier this month, when scientists reported that it might be the first chunk of Mercury ever found here on earth. But scientists who've been puzzling over the stone since then say the accumulating evidence may point in a different direction. The 4.56-billion-year-old rock might have come from the asteroid belt located between Mars and Jupiter. If true, then it would provide clues about the origin of the solar system as a whole instead of the origin of the innermost planet."
