A strange green space rock hailed as perhaps the first meteorite ever discovered from Mercury may be too old to have come from the solar system's innermost planet, some scientists say.

Last month, scientists announced that the green-hued meteorite NWA 7325 shares many chemical similarities with Mercury, suggesting it may be the first known visitor from the small, sun-scorched planet.

But NWA 7325's advanced age — it's thought to be more than 4.5 billion years old — casts some doubt on this interpretation, some scientists have stressed, citing the example of Earth's moon to help make their point.
