Meteor showers occur when the Earth's orbit takes it through the path of a comet, which spews debris as it passes, like junk falling out of the back of a poorly-secured garbage truck. Bits of debris plunge through the Earth's atmosphere, and friction causes the debris to burn up, creating meteors.

Current meteor forecast models project a strong Draconid outburst, possibly a full-blown storm, on Oct. 8, 2011, according to William Cooke of the Meteoroid Environment Office at NASA's Marshall Space Flight Center in Huntsville, Ala.
