Comets are icy objects that orbit the sun. When they get close to the sun, they heat up and the solar wind gives them an atmosphere (called a coma), as well as a tail, making them look like they are burning in the sky.
The name “comet” comes from the Latin word cometa, which in turn comes from a Greek word which means “wearing hair”. Thus, the word “comet” means “star with hair”.
Halley’s Comet is the most famous comet, completing its orbit of the sun every seventy-five years. Its most notable appearance was in 1066, before William the Conqueror invaded England, and is said to have been a sign of his apparent victory.
