Its composition is usually rocky or metallic.

Meteoroids don't enter the earths atmosphere, Meteors do. Meteoroids are the rocks that you find on the ground after a meteor penetrated the atmosphere and made it to the ground.
Meteoroids are small, solid, extraterrestrial bodies that hits the earth's atmosphere.
The mesosphere protects the earth from most meteoroids.
Yes, the mesosphere helps protect Earth from meteoroids by burning up smaller meteoroids as they enter the atmosphere due to friction with gas molecules. This process causes them to disintegrate before reaching the Earth's surface.
We know that there are small meteoroids and dust in space because meteorites (meteoroids that survive the atmosphere and land on Earth) exist, and also because we can see meteoroids as meteors (the light coming from a meteoroid burning up in the atmosphere) in the sky.

The Mesosphere
Meteoroids are more likely to strike Mercury because its proximity to the sun results in a denser population of meteoroids in its vicinity. Additionally, Mercury's lack of a substantial atmosphere means there is no protective layer to burn up meteoroids before they reach the surface. Earth's atmosphere, on the other hand, acts as a shield, causing most meteoroids to burn up before they reach the surface.
