SOLAR SYSTEM

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: -Comets are made of water, ice, dust, and gasses likes carbon monoxide and methane. After identifying what is in the nucleus, you will know what the coma and tail are made of.

Detailed explanation-3: -The solid, core structure of a comet is known as the nucleus. Cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen carbon dioxide, carbon monoxide, methane, and ammonia. As such, they are popularly described as “dirty snowballs” after Fred Whipple’s model.

Detailed explanation-4: -Each comet has a center called a nucleus that contains icy chunks of frozen gases, along with bits of rock and dust.

Detailed explanation-5: -When a comet comes close to the Sun, the ices sublimate (go directly from the solid to the gas phase) and form, along with entrained dust particles, a bright outflowing atmosphere around the comet nucleus known as a coma.

Detailed explanation-6: -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.
