SOLAR SYSTEM

Detailed explanation-1: -A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail.

Detailed explanation-2: -Every comet has a nucleus, a stable, porous central mass of ice, gas, and dust that if often between 1 and 10 kilometers (0.6 to 6 miles) in size. The ice is made of varying amounts of water, carbon dioxide, ammonia, and methane. The dust may contain hydrogen, oxygen, carbon, nitrogen, silica, and some metals.

Detailed explanation-3: -A Comet Has Two Types of Tail One is a plasma trail, which draws a straight line like a broomstick. The other is a dust tail, which opens like the bristles on a broom. The plasma tail comprises electrons and ions that are ionized by the sun’s ultraviolet radiation. The dust tail consists of micrometer-scale particles.

Detailed explanation-4: -The nucleus is the solid, central part of a comet, once termed a dirty snowball or an icy dirtball. A cometary nucleus is composed of rock, dust, and frozen gases. When heated by the Sun, the gases sublime and produce an atmosphere surrounding the nucleus known as the coma.

Detailed explanation-5: -characteristics of comets … comet nucleus known as a coma. As dust and gas in the coma flow freely into space, the comet forms two tails, one composed of ionized molecules and radicals and one of dust.
