Comets have a tail because of the interaction between the comet's nucleus and the Sun's radiation. When a comet gets close to the Sun, the heat causes ice and other volatile substances on the comet's surface to vaporize and create a glowing cloud of gas and dust called a coma. The solar wind then pushes this material away from the comet, forming the tail that points away from the Sun.
