Detailed explanation-1: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
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.
