SOLAR SYSTEM

Detailed explanation-1: -What are the parts of a comet? At the heart of every comet is a solid, frozen core called the nucleus. This ball of dust and ice is usually less than 10 miles (16 kilometers) across – about the size of a small town.

Detailed explanation-2: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices.

Detailed explanation-3: -Comets are like “dirty snowballs” that have orbited the Sun since our Solar System formed, billions of years ago. A comet is really just a round chunk of ice and dust. The ball-like part of the comet is called the nucleus, and its long “tail” is called the coma.

Detailed explanation-4: -As a comet approaches the sun, the “dirty snowball” of the comet’s nucleus sheds gas and dust. The dusty tail may contain hundreds or even thousands of meteoroids and micrometeoroids. Meteoroids shed by a comet usually orbit together in a formation called a meteoroid stream.

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.
