A comet's tail is a stream of gas and dust that is released when a comet approaches the Sun, resulting from the sublimation of its icy nucleus. This tail always points away from the Sun due to the influence of solar wind and radiation pressure, which interact with the comet’s material and push it outward. The formation and orientation of a comet's tail provide insight into the dynamic processes occurring in the solar system as well as the characteristics of the comet itself.
