Solution

Comets Meteors

Comets are heavenly bodies that revolve around the Sun in an elongated orbit. Meteoroids are small rock pieces that revolve around the Sun.

They are usually made up of dust, ice particles and gases. Some meteoroids enter the Earth's atmosphere with a great velocity.

Most comets have a head, a nucleus and a tail. When they approach the Sun, the gases get heated up; as a result they glow. They get heated up due to the friction of the atmosphere. This causes the meteoroids to glow.

Example: Halley Example: Leonid
