Most all comets originate in the Oort Cloud, a theoretical spherical cloud or halo of perhaps several trillions of comets encompassing our solar system and extending up to 465 billion miles from the Sun. Comets are leftover material from the creation of the solar system 4.6 billion years ago. They are irregularly shaped objects, estimated to range in size from several hundred feet to 25 miles and over, composed of ice, small rocks, dust, various gases, and organic compounds.
