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: -A comet’s coma is the atmosphere of gas and dust around the nucleus of the comet. It can be hundreds of thousands of kilometers wide. The coma of a comet is made largely of water and dust. When a comet approaches the Sun, it warms up.
Detailed explanation-3: -The tail consists of gas and dust that can extend hundreds of millions of kilometers away from the coma. Most comets actually have 2 tails: a plasma tail made of ionized gas, and a dust tail made of small solid particles.
