* The Sun: The Sun is a star that emits its own light and heat.
* Planets, Moons, and Asteroids: These objects orbit the Sun and don't produce their own light. They reflect sunlight, which is why we can see them.
Here's a simpler explanation:
Imagine a flashlight shining on a bunch of marbles. The marbles don't make their own light, but they reflect the light from the flashlight, making them visible. The Sun is like the flashlight, and the planets, moons, and asteroids are like the marbles.
