what is a meteor made of
Quatr.us Physics Space. Meteor. Meteors or meteorites are bits of rock (like granite) and ice-usually a mixture of rock and iron and nickel but sometimes just rock or just iron-from out in space that get sucked into the gravity of the Earth and fall through our atmosphere to the ground. meteor is the same thing as a shooting star or a falling star-they're not really falling stars, but some people call them that. Meteors look like stars as they fall because when they hit Earth's atmosphere the friction of the rock rubbing against the atmosphere causes heat and light, like a fire.
