Meteor is a rocky or metallic body in outer space.
Meteors are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies such as the Moon or Mars.
History[]
Traveling back in time to the Cretaceous Period with Jules and Verne, Doc Brown tests his latest invention - a device which effectively disintegrates objects - on a meteor headed for the Earth. Returning to the future, they find themselves in an alternate 1991, where humans don't exist and dinosaurs have developed a human-like civilization. Before they can be erased from existence, the Browns return to the prehistoric era and Doc reintegrates the meteor, restoring the correct timeline.
