Question

Quizplus · Accepted Answer

Asteroids, primarily found in the asteroid belt between Mars and Jupiter, are made of metal and rock, containing fewer volatiles (substances that vaporize at relatively low temperatures) compared to comets. Comets, originating from the Kuiper Belt or the Oort Cloud, have a higher content of ice and gas, which vaporize when they approach the Sun, creating a visible atmosphere or coma and sometimes a tail.
