Meaning
Albedo is a measure of how much solar radiation is reflected and how much is absorbed by a planet.
About Albedo
- The albedo of a planet affects the average temperature of a planet's surface.
- A planet will achieve temperature constancy when it emits the same amount of radiation as it absorbs.
