Asteroids are rocky or metallic. Comets are made mostly of various types of ice, although they also contain some amount of dust and rock mixed in. A rock in space might also be a meteor.
Both asteroids and comets are celestial bodies in space, but they differ in composition and appearance. Asteroids are mainly made of metal and rock, and are found mostly in the asteroid belt between Mars and Jupiter. Comets, on the other hand, are made of ice, dust, and rock, and come from the outer regions of the solar system. Comets also have a tail that forms when they get close to the Sun, while asteroids do not.
Comets are a mix of dust, rock, and ice, while asteroids are primarily made of rock and metal. Comets usually have a tail when they approach the Sun due to the melting of the ice, while asteroids do not have tails.
Comets are composed mostly of ice while asteroids are mostly made of rock or metal.
Comets contain ice.
A comet is a large chunk of ice and rock (sometimes you can find iron there, too) with a large tail of ice. Comets are usually relatively small, and some can be formed from a collision between two asteroids. Comets, if they come in contact with Earth, usually are melted to pebbles from the atmosphere. Asteroids, on the other hand, differ greatly in size. They can be as small as a pebble or as big as a city. They are what astronomers and scientists worry about the most. After all, a large enough asteroid destroyed the dinosaurs. Asteroids have no tail of ice, and have no ice at all. They're made of solid rock and iron. Asteroids and comets have many things in common. They're considered space debris from collisions. They smash into planets and cause impacts. They both are made or rock - and sometimes iron - and dance around through deep space doing nothing at all.
Asteroids and comets are the two space objects that produce meteorites when they enter Earth's atmosphere and survive the descent to reach the surface. Asteroids are rocky objects that orbit the Sun, while comets are composed of ice, dust, and rock.
Asteroids, meteoroids, and comets are space objects that are made of chunks of rock. Asteroids are rocky bodies that orbit the Sun within the asteroid belt, meteoroids are smaller rocky fragments that travel through space, and comets are a mixture of rock, dust, ice, and frozen gases.
Asteroids are composed mainly of rock, metal, or a mixture of the two. Comets are a mixture of ice and rock.

-- meteoroids -- asteroids -- comets -- satellites -- planets (rocky ones)
Asteroids, meteors, comets, or some type of space rock that hit the Moon and causes the crater.
Rock debree from other galaxy's
Not really, you're thinking of comets, asteroids are composed of rock, metal, or a combination of both.
A piece of space rock floating through space is a meteoroid. When it hits the atmosphere and glows white-hot with the heat of friction, it is a meteor.Once it hits the ground, it is a meteorite.
Beacuse asteroids are chunks of solid rock - Comets are primarily lumps of ice - which melts as it nears the sun !
