Browsing: Comet
A comet is a small celestial body composed of ice, dust, and rocky material that orbits the Sun, often in highly elongated paths. When a comet approaches the inner solar system, solar radiation causes its volatile components to vaporize, creating a glowing coma and often a distinctive tail that streams away from the Sun. These dynamic objects are thought to be remnants from the early solar system, preserving clues about its formation and the origins of water and organic compounds on Earth. Studying comets, both through telescopes and space missions, offers scientists a unique window into the primitive materials that shaped our planetary neighborhood.
