Do you know the difference between Asteroids, Comets, Meteorites ?
Well, the bigger rocks are called Asteroids.
The smaller are Meteroids, ...
...and when they fly through the Earth's atmosphere, they're called Meteors.
If they manage to survive their burning descent and land on Earth, we call them Meteorites.
Some meteorites contain Iron, which makes them very dense, dark, and magnetic.
They are the oldest thing you could ever touch, as they are the same age as the Solar system.
