A small body moving in the solar system that would become a meteor if it entered the earth’s atmosphere.
- The term ‘space debris’ in its largest sense includes all naturally occurring remains of solar and planetary processes: interplanetary dust, meteoroids, asteroids, and comets.
- Once the meteoroids enter the Earth's atmosphere, they are known as meteors and become visible due to the friction caused by air molecules slamming against the surface of the high-velocity particle.
- It is probably natural to think of meteorites - as the meteoroids that fall to Earth are called - as threatening, even dangerous, phenomena.
- Example sentences
- The moon, after all, had acted as a gravitational trap for meteoroidal material accumulated from space over many eons.
- It was interpreted as a meteoroidal bolide followed by probable meteorite fall.
- If you have a small telescope, within your grasp are many thousands of craters, ranging from the grand walled plains to meteoroidal and asteroidal impact craters with their bright ray systems.
