Like fugitives on the run from distant solar systems, meteors hurtle through the earth’s atmosphere, lighting up the eyes of observers on the ground. Often these fireballs of metal and rock burn up in a blaze of glory, and many do not survive their impact with the Earth’s surface. Those that do though start a more settled life here on Earth as meteorites. Some might even claim to be the new sheriffs in town – they’re that big and resistant to weathering.
