Explanation:

A meteoroid is a small rocky or metallic body in outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects . A meteor is the visible path of a meteoroid that enters the Earth's (or another body's) atmosphere, commonly called a shooting star or falling star. A meteor is a meteoroid that has entered the earth's atmosphere. It will then become brightly visible due to the heat produced by the ram pressure. If a meteor survives its transit of the atmosphere to come to rest on the Earth's surface, the resulting object is called meteorite.
