The ratio of the amount of stellar/solar radiation or other megascale light source reflected from an object (such as planet, moon, orbital or habitat) to the total amount it receives. The higher the albedo the brighter the object. A white, completely reflecting object has an albedo of 1.0; a black object with no reflectivity has an albedo of 0.0. Icy bodies tend to have a high albedo, sooty bodies a low albedo.
