Here's a breakdown:
* Light: The moon is a large, rocky body that orbits the Earth. It doesn't emit its own light. The light we see from the moon is actually sunlight that is being reflected off its surface.
* Heat: Because the moon doesn't generate its own heat, its surface temperature varies drastically depending on whether it's facing the sun or not. The side facing the sun can get very hot, while the side facing away can be extremely cold.
In short, the moon is like a giant mirror in space, reflecting the sun's light and heat.
