What is a comet?

Quick Answer
A comet is a small icy body that grows a glowing coma and tail when it nears the Sun and its ices vaporise.
The Full Story
Comets are leftover icy debris from the birth of the solar system, made of frozen gases, dust, and rock — often described as dirty snowballs. When a comet travels close to the Sun, the heat vaporises its ices, releasing gas and dust that form a glowing halo called a coma and one or more tails that always point away from the Sun. Most comets originate in distant regions like the Kuiper Belt and Oort Cloud. Halley Comet, which returns roughly every 76 years, is the most famous.
