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.
Sunlight also provides the energy that powers Earthâs climate system. The image above shows Earthâs average albedo for March 2005, measured by the Clouds and Earthâs Radiant Energy System (CERES) instrument aboard NASAâs Terra satellite. Albedo is the fraction of incoming sunlight that our planet reflects back to space. If Earth was covered in ice like a giant snowball, its albedo would be about 0.84, meaning it would reflect most (84 percent) of the sunlight that hit it.
