You're right, the Moon and planets don't produce their own light. They shine because they reflect sunlight. Here's a breakdown:

* The Moon: The Moon is a large, rocky body that orbits Earth. It doesn't produce light like the Sun, but it reflects sunlight that falls on it. We see the Moon because the sunlight bouncing off its surface reaches our eyes.

* Planets: Planets, like the Moon, are also non-luminous objects. They orbit stars, and we see them because they reflect starlight. The amount of light reflected depends on the planet's size, composition, and distance from its star.

In summary:

The Moon and planets are visible to us because they act like giant mirrors, reflecting light from the Sun or their host star. This reflected light allows us to see them in the night sky.
