Detailed explanation-1: -A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail. 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-2: -Asteroids are small rocky planetoids, while comets are formed of frozen gases held together by rocky and metallic material.
Detailed explanation-3: -The main parts of a comet are the nucleus, the coma, and the tail.
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: -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.
