WebIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m … WebThe Earth-Moon distance varies from 363,000 to 405,000 km. This will lead to magnitude variations of ± 0.12 mag. A further way to check this is that the albedo of the Moon is 0.12 and it has a radius of 0.273 times that of the Earth. Therefore the Earth seen from the Moon ought to be ( 0.3 / 0.12) × ( 1 / 0.273) 2 = 33.5 times brighter.
