SUMMARY: To better understand the environment that formed the Earth, Purdue researchers are studying 29 meteorites that formed in our planet's neighbourhood. Scientists believe the Earth collided with a Mars-sized planet early on, which changed its chemical makeup (and helped to form the Moon). These meteorites formed at the same time as the Earth, but they avoided this cataclysmic collision, so they can offer clues which were wiped clean from our planet.

Interesting. By studying the minerals in these rocks, we might learn what Earth would have been like had it not for the great collision. Maybe Earth would have suffered a similar fate as Venus?
