Astronomy In astronomy, brightness is given in a value called magnitude. A -2-magnitude star is 2.512 times brighter than a -1-magnitude star, a -3-magnitude star is 2.512 times brighter than a -2-magnitude star, and so on. If Sirius is magnitude -1.5 and the full moon is magnitude -12.5, how much brighter is the full moon?
