SOLAR SYSTEM

Detailed explanation-1: -Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.

Detailed explanation-2: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

Detailed explanation-3: -Scientists sometimes call comets dirty snowballs or snowy dirtballs, depending on whether they contain more ice material or rocky debris according to NASA. Related: How to view and photograph comets.

Detailed explanation-4: -Comet Encke has the shortest orbital period of any known comet within our solar system. Encke last reached perihelion (closest approach to the sun) in 2015. Comet Enke is the parent comet of the Taurid meteor stream.

Detailed explanation-5: -Comets are large objects made of dust and ice that orbit the Sun. Best known for their long, streaming tails, these ancient objects are leftovers from the formation of the solar system 4.6 billion years ago.
