See also: Meteoroid and Meteor. A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the Earth's atmosphere and impact with the Earth's surface.
Difference between Meteor and Meteorite. Meteoroid that enters the earthâs atmosphere is called a meteorite and the light that is created due to the burning of the meteorites is called a meteor. A meteor shower occurs when several meteorites enter our atmosphere at once and easily get burned up enabling us to see hundreds of meteors depending on where you location.
