Asteroids
Different types of objects exist in the solar system. The heavenly bodies, whether big or small, revolve around the Sun and are members of the solar system. Asteroids are also members of the solar system. The smaller masses of rocks without any specific shape that revolve around the Sun along their orbits are called Asteroids or baby planets. There are too many asteroids in our solar system. Their orbits around the Sun are somewhat irregular, so while revolving around the Sun, they collide with each other.
Comet
Bright tails when coming closer to the Sun are called Comets. Their orbits are highly elliptical, and most of them extend up to the Kuiper Belt. Some comets come very close to the Sun and go very far away while revolving. Many comets do not go outside the Kuiper Belt and are called Endocomets, and some come to revolve around the Sun from outside the solar system, called Exocomet. Comets are composed of ice, dust particles, fragments of rocks, and gases.
