A body of solar system consisting of dust and ice can be identified as Comet. Comets are thought to be made of dust, ice (water, ammonia, methane, carbon dioxide), some organic materials and a rocky center.
As a comet gets closer to the sun, the ice on the surface of the nucleus begins turning into gas, forming a cloud known as the coma. Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet's gases into ions, forming an ion tail. Since comet tails are shaped by sunlight and the solar wind, they always point away from the sun.
