A meteoroid is a solid body in interplanetary space before it reaches the Earth's atmosphere. A meteor denotes the fiery streak or shooting star which appears when a tiny meteoroid strikes the Earth's atmosphere and burns up.Most meteors result from meteoroids no more than a few centimeters in diameter.A larger meteoroid which survives the fiery passage through the Earth's atmosphere as a meteor and strikes the Earth's surface is called a meteorite. Meteoric material less than a tenth of a millimeter in diameter is called cosmic dust.ost meteors are composed of debris left behind by comets as they orbit the Sun. A meteor shower occurs when the Earth intersects a comet's path and moves through the stream of debris and dust emitted by the comet. The meteors in a shower appear to originate from one area of the sky called the radiant.
