Detailed explanation-1: -Meteoroids are objects in space that range in size from dust grains to small asteroids. Think of them as “space rocks.” When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors.
Detailed explanation-2: -Some people call them shooting stars. Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
Detailed explanation-3: -A “falling star” or a “shooting star” has nothing at all to do with a star! These amazing streaks of light you can sometimes see in the night sky are caused by tiny bits of dust and rock called meteoroids falling into the Earth’s atmosphere and burning up.
