For … WebMar 9, 2024 · Or, conversely, a 6th-magnitude star is 100 times dimmer than a 1st-magnitude star. So a difference of 1 magnitude corresponds to a brightness factor of …
WebSixth magnitude stars were assigned to stars that were barely visible to the unaided eye under good conditions. It was then theoretically determined that the ratio of first magnitude to sixth magnitude was 100 to 1. Then a logarithmic scale of 2.512 between magnitude levels is to be implemented.
