* Size: Meteoroids can be tiny, like a grain of sand, or as large as a car.
* Origin: They come from various sources, including:
* Asteroids: Larger bodies that orbit the sun.
* Comets: Icy bodies that release dust and debris as they get close to the sun.
* Mars and the Moon: Fragments ejected from these bodies by impacts.
* Not a planet or a moon: Meteoroids are much smaller than planets and moons and don't have the same characteristics.
The meteoroid's fate:
* Burn up: When a meteoroid enters the Earth's atmosphere, it heats up due to friction and usually burns up, creating a streak of light we call a meteor.
* Become a meteorite: If the meteoroid is large enough to survive the fiery journey, it can hit the ground and become a meteorite.
Here's a simple analogy:
Imagine a small pebble being thrown into a lake. The pebble (meteoroid) is traveling through the air (space) and creates a ripple (meteor) as it enters the water (Earth's atmosphere). If the pebble is large enough, it might actually reach the bottom of the lake (Earth's surface) and become a rock on the lake bed (meteorite).
