I just downloaded the trial version of Astrosynthesis 2.0. I wanted to see how accurate its calculations are (about +/- 25% off).
However, while entering a planet, on the Planet/Moon tab of the Properties box, it has a listing for albedo.
Which Albedo? V or B? There are two albedoes for a celestial object.
V-Albedo is the visual albedo or how much light the object reflects. This is the fraction when comparing the body to a perfectly diffusing object with a phase angle of 0. Commonly abbreviated V-Albedo. Earth's V-Albedo is 0.367.
B-Albedo is the bond albedo or how much energy the objects reflects without absorption. This is the fraction when comparing the body to a perfectly black body. Commonly abbreviated B-Albedo. Earth's B-Albedo is 0.306.
There is a major difference between the two. Specifically, most astronomers (myself included) refer to an object's B-albedo because this albedo is biggest determinant for the object's global average surface temperature (GAST) whether the object has an atmosphere or not. V-albedo is used to determine the object's absolute magnitude when determining how bright or dim the object is from certain distances.
Thus, I ask again: Which Albedo?
