Planets, Comets, Asteroids and Dust

Asteroids and comets are considered remnants from the huge cloud of gas and dust that condensed to generate the sun, planets, and moons certain 4.5 billion years ago. Today, most asteroids orbit the sun in a tightly packed belt located between Mars and Jupiter. And when detected through a telescope, comets appear fuzzier.
