No, the Moon doesn't reflect all sunlight falling on it. It actually reflects only about 7% of the sunlight that hits its surface. This is why it appears so much dimmer than the Sun.

Here's why:

* Surface composition: The Moon's surface is covered in dust and rocks, which are relatively dark and absorbent.

* Angle of incidence: The angle at which sunlight hits the Moon's surface affects how much light is reflected. Light hitting at a more direct angle is more likely to be reflected.

The 7% figure is an average. Different parts of the Moon reflect light differently. The dark, flat areas called maria reflect less light than the brighter highlands.
