Explanation:
Detailed explanation-1: -Because sunlight and solar wind always flow outward from our Sun’s surface, the tails always point away from our Sun no matter what direction the comet is moving in its orbit.
Detailed explanation-2: -However, as the comet moves away from the sun, the tail is in front. The tails of some comets are large enough and reflect enough light to be visible from Earth. As the comet continues its orbit and gets farther from the sun, the tail disappears from sight.
