Question

Have you ever seen in the evening or in the predawn hours a large celestial body with a long tail? What is it called?

Answer 1

It is called a comet. A comet is a celestial body made of ice and dust particles. It revolves around the Sun. When a comet comes close to the Sun, the Sun’s heat turns some frozen matter into gas. This gas forms a long tail, so the comet appears bright with a long glowing tail.
