Is this a phone number calling you that you're trying to identify?
The term used to describe how to measure how reflective the surface is, is the surface albedo. Surface albedo represents the ratio of irradiance reflected to the irradiance recieved by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of a solar radiation reaching the Earth's surface.
Because the Moon<span> rotates </span>on<span> its axis at the same rate that the </span>Moon<span> orbits the </span>Earth<span>, </span>a<span> situation known as synchronous rotation or tidal locking. The </span>Moon is <span>directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.
Hope this helps :)
