When happens to the tail and coma of a comet after the comet passes perihelion?

Question

Quizplus · Accepted Answer

As a comet gets closer to the Sun, the heat causes ice and other materials on the surface to sublimate or vaporize, creating a cloud of gas and dust around the nucleus called a coma. This cloud is pushed away from the Sun by solar winds, creating a tail. After the comet passes perihelion and moves away from the Sun, it cools down, and the rate of sublimation decreases. As a result, the tail and coma shrink.
