Detailed explanation-1: -Asteroids are rocky, airless worlds that orbit our Sun. They are remnants left over from the formation of our solar system, ranging in size from the length of a car to about as wide as a large city. Asteroids are diverse in composition; some are metallic while others are rich in carbon, giving them a coal-black color.
Detailed explanation-2: -Small asteroids are known as meteoroids. When a meteoroid enters the atmosphere of the Earth, it is called a meteor. If any of the meteor survives its trip and lands on Earth, we call it a meteorite.
Detailed explanation-3: -A small fraction of main-belt asteroids have orbits that cross the orbits of the inner planets. These are called near-earth asteroids, and are a major source of the meteorites that occasionally fall to earth. Asteroids with orbits that approach the earth, passing inside the perihelion of Mars, are called Amors.
