Comet and Sun,artwork. Comets are bodies of ice and dust that enter the inner solar system from the outer solar system. As they approach the Sun,the heat boils the ice,producing a coma around the nucleus,along with a tail stretching out behind it. This tail has two components,both shown here: a gas tail (blue) and a dust tail (white). The blue colour of the gas tail (actually an ionised plasma) is usually due to the presence of carbon monoxide ions. The gas tail points directly away from the Sun,while the dust tail is less affected by the solar wind and usually curves to one side | |
