SOLAR SYSTEM

Detailed explanation-1: -According to the story, comets are new objects that come from the remote corners of the Solar System. Like planets, comets also orbit round the Sun, but their orbits are highly eccentric. Once in a while, a comet comes close to the Sun.

Detailed explanation-2: -What is a comet? Comets have been likened to dirty snowballs, and that’s a pretty apt description. They’re loosely bound masses of ice, dust and rock. The core or nucleus of a comet is relatively small-often just a few miles across.

Detailed explanation-3: -Comets are celestial objects made of gas and dust which revolve around the Sun in a highly elliptical orbit. They are visible only when they approach closer to the Sun. The revolution period of a comet is very long.

Detailed explanation-4: -Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers”-made from materials from the formation of our Solar System 4.5 billion years ago.
