SOLAR SYSTEM

Detailed explanation-1: -Every comet is made of the same basic ingredients–ice and dust. However, comets vary in how much of the ice is water ice and how much is ice made of other substances, including methane, ammonia, carbon dioxide, carbon monoxide, sulfur, and hydrogen sulfide.

Detailed explanation-2: -Orbit of a Comet. 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-3: -Comets are small icy dirtballs that orbit the Sun; comets are made of ice and dust while asteroids are made of rock).

Detailed explanation-4: -Asteroids, which are mostly rocky, do not usually form tails when they approach the Sun. Comets, however, are a mix of ice and rock, and typically do form tails as the Sun vaporizes their ice, blasting material off their surfaces and leaving a trail along their orbits.
