Meteoroids are incredibly tiny, stony bodies that revolve around the sun. As with planets, asteroids, and comets, rocks or iron chunks called meteoroids orbit the sun.
As a meteoroid enters the atmosphere, friction warms it up, producing a brilliant trail of hot ionized gases (plasma) known as a meteor. If the item survives both its entry into the atmosphere and its landing on the ground, it is referred to as a meteorite. Asteroid pieces make up more than 99 percent of meteorites. A tiny group is known to have come from the moon, and another group is widely believed to have originated on Mars. Although it hasn't been proven conclusively, there is also grounds to think that some are pieces of comets rocky debris.
