He aquí por qué:

* Albedo is a measure of how much light a surface reflects. It's a percentage, with 0% meaning no reflection (like a black hole) and 100% meaning all light is reflected (like a perfect mirror).

* High albedo means the surface reflects a large amount of light. Think of fresh snow, which appears very bright because it reflects a lot of sunlight.

* Low albedo means the surface absorbs more light and reflects less. Dark asphalt, for example, has a low albedo and absorbs a lot of sunlight, making it appear darker.

Por lo tanto, un objeto con un albedo alto parecerá más brillante que un objeto con un albedo bajo porque refleja más de la luz que lo golpea.
