Green fireballs

Have you ever seen a green fireball in the sky? It's pretty cool! These green fireballs are like shooting stars but with a special green color.

So, how do they happen? It starts with something called a meteor. A meteor is a piece of rock or metal from space that enters Earth's atmosphere. When it enters the atmosphere, it gets super hot and starts to glow. This is what makes shooting stars!

But sometimes, a meteor can become special. When it travels very fast through the atmosphere, it can ionize the air around it. This means that it takes electrons away from the air molecules and makes them glow. And when this happens, we see a green fireball!

Scientists believe that these green fireballs are caused by meteors made of a certain type of rock called "green stone." When a green stone meteor enters the atmosphere, it creates the ionization and glowing air, which gives it the unique green color.

So, next time you see a green fireball, remember that it's a special type of shooting star caused by a special type of rock from space!
