Albedo objects in the outer Solar System and asteroid belt have low albedos down to about 0.05. A typical comet nucleus has an albedo of 0.04. Such a dark surface is thought to be indicative of a primitive and heavily space weathered surface containing some organic compounds. The overall albedo of the Moon is measured to be around 0.136, but it is strongly directional and non-Lambertian, displaying also a strong opposition effect. Although such reflectance properties are different from those of any terrestrial terrains, they are typical of the regolith surfaces of airless Solar System bodies. Two common albedos that are
Albedo 0.39 Albedo 0.39 Albedo 0.39 is a studio album by the Greek electronic composer Vangelis, released in 1976. It was the second album produced by Vangelis in Nemo Studios, London, which was his creative base until the late 1980s. It contrasts with his previous album, "Heaven and Hell", which was classically inspired and choral, while "Albedo 0.39" has blues and jazz overtones. It was his first Top 20 UK album. It is a concept album themed around space physics (the reflection of light i.e. physical truth). Its title is inspired by the idea of a planet's albedo, the proportion of the
