What are sky full of stars?

The sky is full of stars because they are like tiny lights far away in space.

Imagine you're sitting on a big pillow at night, and all around you are little flashlights that someone turned on, but they’re so far away, it looks like they’re just glowing points in the dark. That’s what stars are like: tiny lights in the sky, very, very far from us.

Stars are like big balls of fire, burning super hot inside. They're not made of paper or plastic, they're made of gas, and they’re so big that our whole Earth could fit inside one!

During the day, the Sun is so bright it hides all the other lights in the sky. But when it gets dark, those faraway stars become visible, like tiny lights on a giant blackboard.

Sometimes you can even see the Moon, that’s another big light in the sky, but it's not a star; it's more like a big ball of dirt and rocks, shining because it reflects the Sun's light.
