Detailed explanation-1: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.
Detailed explanation-2: -What is a comet? Comets are collections of rocky material and ices, sometimes referred to as “dirty snowballs”. One of their key features is their large abundance of so-called “volatile” compounds, things like carbon dioxide, water and noble gases that sublimate (change from solid to gas) very easily.
Detailed explanation-3: -Comets are made up of mostly ice and dust and are known for the tail of gas and dust that gets blown away from them when they’re near the sun.
Detailed explanation-4: -Comets are frequently called “dirty snowballs” because they consist of mostly water ice, peppered with rocky debris and frozen gases.
Detailed explanation-5: -Comets are small, irregularly shaped bodies in the solar system composed mainly of ice and dust that typically measure a few kilometers across. They travel around the sun in very elliptical orbits that bring them very close to the Sun, and then send them out past Neptune.
