* Planets: Planets are large celestial bodies that orbit a star. They don't produce their own light. Instead, they reflect the sunlight that falls on them. The amount of light reflected depends on the planet's composition, size, and atmosphere.
* The Moon: The moon is a natural satellite that orbits the Earth. It also doesn't generate light. The moon's surface is covered in dust and rock, which reflects sunlight back towards us.
Think of it like this: imagine a mirror reflecting the sunlight. The mirror itself isn't producing light, but it's reflecting the light that shines on it. Planets and the moon work in a similar way.
