A meteorite is a solid piece of debris from a source such as an asteroid or a comet, which originates in outer space and survives its impact with the Earth's surface. It is called a meteoroid before its impact. A meteorite's size can range from small to extremely large.
A meteor is a meteoroid â or a particle broken off an asteroid or comet orbiting the Sun â that burns up as it enters the Earth's atmosphere, creating the effect of a shooting star. Meteoroids that reach the Earth's surface without disintegrating are called meteorites.hen Meteors enter the Earth's atmosphere from outer space, the friction caused by air particles heats them so that they glow, leaving behind them a trail of gas and melted particles as they disintegrate 30 to 60 miles from the ground.
