When they fall into our atmosphere, friction from hitting air molecules causes them to burn and glow (shooting star). Meteoroids that glow are called meteors.When they fall into our atmosphere, friction from hitting air molecules causes them to burn and glow (shooting star). Meteoroids that glow are called meteors.
