Comets are cosmic snowballs of frozen gasses, rock and dust that orbit the sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the sun, it heats up and spews dust and gasses that form a tail that stretches away from the sun fr millions of miles. There are probably billions of comets orbiting our sun in the Kuiper Belt and even more distant Oort Cloud. Comets have right for its name and had best to orbit the sun in the Kuiper Belt.
