The albedo, (Latin for white) is a measure of reflected sunlight. Charcoal has an albedo of 0,04; snow 0,9 The planet with the highest albedo is Venus, whereas Mercury is theâ¦ lowest.
The balance between energy absorbed by the earth and energy reflected back into space is fundamental in determining how warm or cool the planet becomes. The proportion of radiation reflected away by a surface is called its albedo. Albedo can range between 0 (no reflectance) and 1 (complete reflectanceâlike a mirror). The earthâs average albedo is .31, which means that, overall, the planet reflects about 31% of incoming solar radiation back into space.
