Detailed explanation-1: -Answer : 1. B. Comets are ball of ice, dust, and metal.
Detailed explanation-2: -An asteroid is a rocky object that orbits the Sun. Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. Comets are small icy dirtballs that orbit the Sun; comets are made of ice and dust while asteroids are made of rock).
Detailed explanation-3: -Comets orbit the Sun, like asteroids. But comets are made of ice and dust-not rock. As a comet’s orbit takes it toward the Sun, the ice and dust begin to vaporize. That vaporized ice and dust become the comet’s tail.
Detailed explanation-4: -Scientists sometimes call comets dirty snowballs or snowy dirtballs, depending on whether they contain more ice material or rocky debris according to NASA. Related: How to view and photograph comets.
Detailed explanation-5: -The biggest space rocks are asteroids. Asteroids are made up of rock and iron like the four planets closest to our sun, but they are much smaller. All the asteroids put together would be smaller than our moon. Asteroids are different from comets, which are mostly rock and ice.
