Detailed explanation-1: -The solid, centrally located part of the comet is known as the “nucleus". The nucleus is a repository of dust and frozen gases. When heated by the sun, the gases sublimate and produce an atmosphere surrounding the nucleus known as the coma which is later swept into the elongated tail.
Detailed explanation-2: -Comets are like dirty snowballs, made mainly of ice and frozen carbon dioxide with some dust and organic molecules, left over from the formation of the Solar System. They’re like “time capsules, ‘’ telling us what conditions were like in our Solar System 4.5 billion years ago, when the Sun and planets were first forming.
Detailed explanation-3: -A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail.
Detailed explanation-4: -The volatile composition of comets is usually dominated by water (H 2 O), with carbon dioxide (CO 2 ) and carbon monoxide (CO) also being abundant at the 1–20% level compared to H 2 O [5, 6].
