What do you mean by asteroid and metaroids

Asteroids are called minor planets of the inner solar system. There are millions of asteroids in the asteroid belt. More than, 750,000 are found in the asteroid belt, which is located between Jupiter and Mars. Asteroids can be as wide as hundreds of kilometres. Most asteroids are made of rocks, but with the latest explore some are found to be composed of iron and nickel.

A meteoroid is a small rock composed of a metal in outer space. They are significantly smaller than asteroids with size ranging from a millimetre to a meter wide. When meteoroids enter the atmosphere of earth, they eventually vaporize completely and might never reach the surface. They burn during descent and creates a light trail.
