Few things give even a casual star gazer as much heart-jumping excitement as spotting a meteor. Meteors, sometimes called shooting or falling stars, are actually not stars at all. A meteor is created when a tiny piece of space junk (for example, a bit of dust or rock) enters the earth's atmosphere. As this small piece of debris flies high through the air, it encounters friction that makes it so hot it will burn up. As a result, a meteor appears as a quick, bright streak across the sky, and will then disappear. The brighter and longer the streak, the bigger the rock or dust particle that burned up.
