Perseid meteors appear to originate out of the constellation of Perseus. From this gnarl area meteors streak across the sky in all directions. The Perseids meteors are small particles, typically less than the size of a small pebble, moving at over 130000mph. These particles are left behind as the comet Swift-Tuttle orbits the sun. As they enter Earth's atmosphere the particles begin to heat up and then burn across the night sky.
