* The Sun: The sun is a giant ball of hot gas that produces its own light and heat through nuclear fusion.
* Stars: Stars are also giant balls of hot gas that produce their own light and heat, also through nuclear fusion.
* The Moon: The moon is a large, rocky body that orbits the Earth. It doesn't have its own source of light. We see the moon because its surface reflects sunlight.
Think of it like this: Imagine a mirror in a dark room. The mirror doesn't produce its own light, but it reflects the light from a lamp in the room, making it appear bright. The moon acts similarly, reflecting sunlight back to Earth.
