Comets are balls of rock and ice a few kilometers in diameter. They reside in the outer regions of the Solar System. They often have highly elongated orbits that, every many years, bring them close to the Sun. When this happens, the ice that composes them sublimates into gases, forming their characteristic tails, which can extend for millions of kilometers, always in the opposite direction of the Sun as the solar wind pushes them. When Earth crosses the orbit of these comets, their fragments enter our atmosphere, producing what we know as meteor showers or meteor storms. After their spectacular visits, comets give us exciting displays.
