SOLAR SYSTEM

Detailed explanation-1: -Nucleus. A comet nucleus is the solid core of a comet consisting of frozen molecules including water, carbon monoxide, carbon dioxide, methane and ammonia as well as other inorganic and organic molecules-dust. The nucleus of a comet is usually around 6 miles (10 kilometers) across or less (opens in new tab).

Detailed explanation-2: -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 nuclei of most comets are believed to range from 1-10 kilometers (. 6-6 miles) in diameter.

Detailed explanation-3: -The solid nucleus or core of a comet consists mostly of ice and dust coated with dark organic material, according to NASA, with the ice composed mainly of frozen water but perhaps other frozen substances as well, such as ammonia, carbon dioxide, carbon monoxide, and methane.

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: -features of comets The nucleus is a solid body typically a few kilometres in diameter and made up of a mixture of volatile ices (predominantly water ice) and silicate and organic dust particles.

Detailed explanation-6: -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.
