A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock. “ Comet ” comes from the Latin “ cometes ”, which in turn comes from the Greek “ kometes ”, meaning “ long-haired ”. A comet has four components: a nucleus, a coma, a dust tail and an ion tail.

Like planets, some comets orbit the sun on a predictable schedule. Halley's Comet, the most famous of these weird wanderers, drops by Earth every 75 years or so (it’s not due for its next visit until July 2061). As a comet nears the sun, ice and dust boil from its slushy center—called a nucleus—to form an atmosphere known as a coma.
