Answer:
In fact, the moon is one of the least reflective objects in the solar system. The DSCOVER spacecraft captured this single photograph of the moon and the earth. Both the earth and the moon are illuminated by the same amount of sunlight coming from the same angle in this photo.
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
