When the first rock and dust samples from the moon were returned, many folks were surprised because they were dark gray, almost black. We think of the moon as light colored because it's the brightest thing we see in a dark sky, but in actuality it's not very reflective. In fact, on average, the surface of the moon only bounces about 7% of the sunlight back. That's about as reflective as asphalt.
