Astroids, Comets, Meteorites
By: Jared BAier
A small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
A small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a streak of light.
A solid piece of debris, from such sources as asteroids or comets, that originates in outer space and survives its impact with the Earth's surface.
Halley is the only short-period comet that is clearly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime.
