SOLAR SYSTEM

Detailed explanation-1: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet’s orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.

Detailed explanation-2: -Comets have been called “dirty snowballs.” They are small celestial objects, made of ice, gas, dust, and a small amount of organic material, that orbit our Sun.

Detailed explanation-3: -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-4: -From the study of spectrograms, it is known that comets are made largely of compounds of carbon, oxygen, nitrogen, and hydrogen. These compounds include water, ammonia, methane, carbon monoxide, and smaller amounts of other, more complex compounds. The dust in comets is composed of silicates and some metals.

Detailed explanation-5: -The rocky material that formed Earth in the first place contained some water. But that probably doesn’t account for all the water. Comets are mostly water ice.
