Geometric albedo From Wikipedia, the free encyclopedia Jump to: navigation, search ...
Geometric Albedo Ratio of the flux received from a planet to that expected from a perfectly reflecting Lambert disk of the same size at the same distance at zero phase angle (cf. Bond albedo). Geometric Position ...
Geometric albedo is the ratio of a body's brightness at zero phase angle to the brightness of a perfectly diffusing disk with the same position and apparent size as the body. Reference: ...
Asteroid visual geometric albedos range from just under 0.02 to over 0.5 and may be divided into four albedo groups: low (0.02-0.07), intermediate (0.08-0.12), moderate (0.13-0.28), and high (greater than 0.28).

Within this category, visual albedo refers to radiation only in the visible part of the spectrum, whereas geometric albedo, also known as physical albedo, is the ratio between the brightness of an object as seen from the direction of the Sun, ...
Bond albedos - total radiation reflected from an object compared to the total incident radiation from the Sun. Geometric albedos - the amount of radiation relative to that from a flat Lambertian surface which is an ideal reflector at all wavelengths.
