Answer:
Comets have two tails because escaping gas and dust are influenced by the Sun in slightly different ways, and the tails point in slightly different directions. Gases escaping from the comet are ionized by the ultraviolet photons from the Sun.Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler's Laws - the closer they are to the Sun, the faster they move.a gas or ion tail and a dust tail extend from the comet, pushed away from the sun by the solar wind and radiation pressure. boulder-sized and smaller pieces of rock and metal in space are called meteoroids. When a meteoroid enters Earth's atmosphere, it produces a fiery trail, and it is then called a meteor.When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets. The dust and gases form a tail that stretches away from the Sun for millions of miles.comets
Most comets have two tails. The tails appear as the comet approaches the Sun. Sunlight pushes on things, but very gently. Because the comet dust particles are so small, they are pushed away from the Sun into a long tail.
