A group of unusual meteorites was found in Shergotty, India. Their structure indicates that they originated on one of the geologically active planets, Mercury, Venus, or Mars. Because of Mercury’s proximity to the Sun, any material dislodged from that planet’s surface would have been captured by the Sun, rather than falling to being dislodged from Mars, perhaps as the result of a collision with a large object.
