What is a planet’s albedo?

SpacePlanet properties

Quick Answer

A planet’s albedo is the fraction of sunlight it reflects back into space.

The Full Story

Albedo is a measure of reflectivity, usually expressed as a number from 0 to 1 or as a percentage. A high-albedo world reflects a lot of light, while a low-albedo world absorbs more and appears darker. Venus has one of the highest albedos among planets because its thick cloud layer reflects sunlight strongly. The Moon’s comparatively low albedo is one reason it looks dimmer than many people expect.

Key Facts

1.Albedo measures reflectivity
2.Venus is highly reflective because of clouds
3.Dark surfaces have low albedo
