Questions about the extent to which an astronomic object reflects light or other electromagnetic radiation. Consider using the tag "photometry".
The albedo of an object is the extent to which it reflects light, defined as the ratio of reflected to incident electromagnetic radiation.
The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time composes a major part of the astronomical field of photometry.
