The moon doesn't reflect *all* of the light that hits it. It's a relatively poor reflector, reflecting only about 7% of the sunlight that hits it.

That being said, there are times when the moon appears brighter than others:

* Full Moon: During a full moon, the entire face of the moon is illuminated by the sun. This is the time when we see the most reflected light from the moon.

* Lunar Perigee: When the moon is closest to Earth in its orbit (perigee), it appears slightly larger and brighter.

* Opposition: When the sun and moon are on opposite sides of Earth, the moon appears especially bright because the sun's light is shining directly onto the face of the moon that's facing Earth.

It's important to remember that the moon doesn't produce its own light; it simply reflects sunlight.
