Correct Answer: Comets

Solution : The correct option is Comets .

Cosmic snowballs of frozen gases, rock, and dust that orbit the Sun are known as comets. Comets are small celestial bodies that develop a bright, glowing coma (a fuzzy, cloud-like shell) and, sometimes, a tail when they come close to the Sun. The heat from the Sun causes the ice in the comet to vaporize and release gas and dust, creating the characteristic features observed from Earth.
