Given the absolute magnitude and the distance to a star, the apparent magnitude can be calculated by: <math>m = M + 5((\log_{10}D)-1)</math> where D is the distance in Parsecs (must be adjusted for extra galactic objects). Thus [[Antares (star)|Antares]] at M -5.28 as seen from [[Capital (world)|Capital]] (distance of ~38 parsecs) would be:<br><math>m = -5.28 + 5((\log_{10}38)-1)</math><br><math>m = -5.28 + 5(1.58-1)</math><br><math>m = -5.28 + 5(0.58)</math><br><math>m=-5.28 + 2.9</math><br><math>m=-2.38</math> | Given the absolute magnitude and the distance to a star, the apparent magnitude can be calculated by: <math>m = M + 5((\log_{10}D)-1)</math> where D is the distance in Parsecs (must be adjusted for extra galactic objects).
