Meteoroids are typically composed of rock and metal, such as iron and nickel. Ice can also be present in some meteoroids, particularly those originating from comet fragments.
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.

A meteoroid is a small rocky or metallic body in outer space. Meteoroids can come from various sources, but the options are limited by your question. Assuming you're asking about sources that are not typical for meteoroids, the answer would be: Planets: Planets are not a source of meteoroids. Meteoroids are usually fragments of comets or asteroids. They can also be generated from collisions between larger bodies in space. Planets are much larger objects and don't typically break apart to become meteoroids. The common sources of meteoroids are comets and asteroids. When comets get close to the Sun, they release dust and gas, creating a debris trail. If Earth passes through this trail, the debris can enter our atmosphere and create meteor showers. Similarly, asteroids can collide or break apart due to various factors, leading to the creation of meteoroids.

Meteoroids, Meteors & Meteorites.
They are shooting stars
Meteoroids are big lumps of rock in space.
Meteoroids burn up in the Mesosphere. Even though the Mesosphere is the coldest layer, the meteoroids burn up from getting too cold. Meteoroids are also more commonly known as "shooting stars".
meteoroids
Meteoroids are small, solid, extraterrestrial bodies that hits the earth's atmosphere.
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.

a circular depression in the ground caused by a meteoroids is called a crater
