<P> Moonlight consists of mostly sunlight (with little earthlight) reflected from the parts of the Moon's surface where the Sun's light strikes . </P> <P> The intensity of moonlight varies greatly depending on its phase, but even the full Moon typically provides only about 0.05--0.1 lux illumination . When the Moon is at perigee and viewed around upper culmination from the tropics, the illuminance can reach 0.32 lux . The full Moon is only about one - millionth as bright as the Sun . </P>

Where does the light from the moon come from
