'''Albedo''' is the reflection coefficent of an object to electromagnetic radiation (usually visible [[light]]). The word comes from '''albus''', ''Latin'' for white.
Albedo is not expressed in any units but on a scale from 0 to 1. A pure white object would be 1 while completely black object (e.g. [[black hole]]) would have a value of zero. It is an important concept in climate change discussions where the albedo of the earth affects the amount of light and heat reflected back in to space.
The moon has an albeod of 0.39.
