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.

Detailed explanation-2: -The asteroids that are nearest the sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock. Silicates are the are very common on Earth and in the solar system.

Detailed explanation-3: -Asteroids are space rocks that have existed since the formation of the planets over 4.6 billion years ago. Scientists believe that asteroids are pieces of rock that were never swept up into planets. Like the planets, asteroids are kept in orbit by the gravity of the Sun.

Detailed explanation-4: -A meteoroid is a small piece of asteroid or a comet, typically pebble-sized, but could be a little smaller or a little larger, and often created from a collision.. When a meteoroid gets close to the Earth and enters the Earth’s atmosphere, it’s called a meteor.
