How do astronomers know about meteorites?
Not just astronomers, but everyone knows about meteors and meteorites. You can see them. As Earth goes around the sun, every so often it will travel through a part of space that has lot’s of dust and tiny debris particles in it. As these tiny dust particles travel through our atmosphere, they burn up and glow really brightly in the night sky. These are called meteors. If one is large or dense enough to make it to the ground, it’s given a new name – a meteorite. Most are tiny though – like the size of a grain of sand.
