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.
Typically, asteroids are silicates (rocks) and water (in the form of ice), which is pretty much the same stuff that comets are made of, except that the big, beautiful comets are mostly water, and the asteroids are mostly rock. Asteroids may also have some metals and someday these may be commercially valuable.
