What are Meteors?
 
Unlike comets which are are balls of ice and cosmic dust, meteors are chunks of rock, often from the clumping of cosmic dust, or chips off of asteroids.  They are quite small too, usually being the size of a peanut. To clear things up, a meteor is the object streaking across the sky, and a meteorite is the fragment that is recovered from Earth.  On August 25th, 1995, a huge meteor between the size of a baseball and basketball fell to earth.  Those are usually rare, and are commonly known as shooting stars.  When meteors enter Earth's atmosphere, they hit it with the speed of fifty times the velocity of a bullet.  Because this is so fast, they also burn up quickly too.  Not as brilliant as a comet, they still have a long tail of gases and chemicals that quickly burns up when it hits the atmosphere.
