Detailed explanation-1: -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.
Detailed explanation-2: -As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. The streams of dust and gas each form their own distinct tail, pointing in slightly different directions.
Detailed explanation-3: -The comets and asteroids that get ejected from our Solar System fly through interstellar space, where they will someday pass near other stars.
Detailed explanation-4: -The tail is pushed out by the Sun’s solar wind. What keeps the comet in motion and guides its path is the gravity from all the planets and stars it passes. When a comet is in our solar system, most of the gravity affecting the comet’s motion is due to the Sun.
