"Comets and Asteroids" are the two celestial bodies orbit the Sun.
Step-by-step explanation:
Asteroids comprise of metals and rocky matter while comets consist of ice, dust, and rocky material. The key difference among asteroids and comets, as in what they are made of, is their structure. These were created some 4.5 billion years ago early in the history of the solar system.
Comets circle the Sun much as planets and asteroids do, except that a comet typically has a very extended orbit. When the comet hits the Sun, a few of the ice begins melting and cooling off, together with dust particles. Such particles and gases surround a ring, called a coma, around the ring.
