Solve the puzzle below to find the cache


A binary star is a star system of two stars orbiting their common center of mass. The brighter star is called the primary and its companion star, secondary. These stars are currently identified by numbers and not by name. Therefore, and for the purpose of this exercise, I have labeled them as follows: “Artemis and Diana.” Artemis is located at 45 30.726 75 29.417 while Diana is at 45 29.646 75 29.417.

The following web address: "http://lasp.colorado.edu/education/outerplanets/math/extrasolar_masses.php, provides a video on how to identify the location of the center of mass between two binary stars. Find the center of mass for these two stars of equal mass and you will find the cache.
