You must take into account that a POINT is dimensionless, therefore amount of light it radiates is zero (0). The full Moon as whole has mean magnitude -12.78 (for mean distance 384,400 km from the center of mass of Earth-Moon system). >Matson: >I believe the moon has an Albedo of less than 10% -- 7% sticks in my >head Remark on albedo: Mean albedo is near to 7 % (exactly 0.067), but varies between 0.05 (the darkest part of Mare) and 0.12 (highlands). -- Mgr.
