SOLAR SYSTEM

Detailed explanation-1: -dust tail: up to 10 million km long composed of smoke-sized dust particles driven off the nucleus by escaping gases; this is the most prominent part of a comet to the naked eye; ion tail: up to 100 million km long composed of plasma and laced with rays and streamers caused by interactions with the solar wind .

Detailed explanation-2: -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. Comet tails point away from the Sun.

Detailed explanation-3: -Plasma tails can stretch tens of millions of kilometers into space. Rarely, they are as long as 150 million kilometers (almost 100 million miles).

Detailed explanation-4: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

Detailed explanation-5: -The Short Answer: 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.
