Detailed explanation-1: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.

Detailed explanation-2: -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-5: -Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. Comets are small icy dirtballs that orbit the Sun; comets are made of ice and dust while asteroids are made of rock).
