The asteroids that enter the path of the earth are called meteoroids. Meteoroids are objects in space that range in size from dust grains to small asteroids.

When meteoroids enter the earth’s atmosphere, they begin to burn, giving out a bright streak of light. They are then known as meteors.

When the meteor does not burn completely, it strikes the surface of the earth, and is called a meteorite. On hitting the ground, it may create a depression called crater.
