Key Parts of a Comet

COMPONENTS OF A COMET


 


Why Are Comets Important?

They are the oldest, most primitive bodies in the solar system.
They are remnants preserved from the earliest days of sun, star and planet formation.
They contain volatile, light, organically rich elements and may provide clues about the building blocks of our solar system.
The impact of a large comet could cause major changes in the climate of a planet or a moon. They may even have caused the extinction of dinosaurs.
