SOLAR SYSTEM

Detailed explanation-1: -Plasma or ion tail: the plasma or the ion tail as many would refer to it is made up of ions which are charged. The dust tail: the dust tail of a comet is often seen to be very wide and long. The envelope tail: among the three tail parts of the comet, the envelope tail is made up of hydrogen gas.

Detailed explanation-2: -The plasma tail is often blue because it contains carbon monoxide ions. Solar ultraviolet light breaks down the gas molecules, causing them to glow. Plasma tails can stretch tens of millions of kilometers into space.

Detailed explanation-3: -Alternatively known as the ‘ion tail’ or ‘plasma tail’, the gas tail of a comet generally starts to form somewhere around the orbit of Mars. Here, the Sun begins to heat the nucleus of the comet releasing gas and dust into a temporary atmosphere called the coma.

Detailed explanation-4: -Comet tails will always point away from the sun because of the radiation pressure of sunlight. The force from sunlight on the small dust particles pushing them away from the sun is greater than the force of gravity acting in the direction toward the sun.

Detailed explanation-5: -The Nucleus. The nucleus, or body, of a comet has been described as a dusty snowball consisting of tiny pieces of rocky material embedded in a mass of ice and frozen gases. The Coma and Hydrogen Cloud. The coma is a cloud of gases that surrounds the nucleus of a comet. The Tail. What are Comets Made Of?
