SOLAR SYSTEM

Detailed explanation-1: -But when a comet gets close to the Sun, it starts heating up. Eventually, the ice begins to turn to gas. This can also cause jets of gas to burst out of the comet, bringing dust with it. The gas and dust create a huge, fuzzy cloud around the nucleus called the coma .

Detailed explanation-2: -The gas (water vapor, carbon monoxide, carbon dioxide, and traces of other substances) and dust forms an “atmosphere” around the nucleus called a “coma.” Material from the coma gets swept into the tail.

Detailed explanation-3: -The nucleus contains icy chunks, frozen gases with bits of embedded dust. A comet warms up as it nears the Sun and develops an atmosphere, or coma. The Sun’s heat causes the comet’s ices to change to gases so the coma gets larger. The coma may extend hundreds of thousands of kilometers.

Detailed explanation-4: -The head of a comet is called the coma. The coma surrounds the snowball like core called the nucleus. The coma is a spherical cloud of dust and gas that is ionized as the nucleus of the coma reacts with the energy from the Sun.
