... Magnitude system was invented by Hipparchus (190-120 BC) – he ranked stars by their apparent brightness from ‘first magnitude’ (brightest) to ‘sixth magnitude’ (dimmest). Bright stars have low magnitudes (measure of faintness). A difference of 5 magnitudes corresponds to a factor of 100 in brightnes ...
