The cache is not at the published coordinates; it is within two miles of them. This puzzle is based on an idea that my 6-year-old son had. He also placed the container.
To calculate the cache coordinates, locate the following planets in their two-dimensional projection and add or subtract their coordinates (divided by 1000) to or from the minutes of the published coordinates (you can ignore the degrees, i.e. 42 and 71, which won't change). I have added in parentheses behind each planet whether the latitude/longitude that I used ends in an even or odd number so that you won't end up being off by 1 on a lot of them.
Aargau (even lat/even long)
Anobis (odd/even)
Coruscant (even/even)
Csilla (even/even)
Cularin (even/odd)
Esfandia (even/even)
Fresia (odd/even)
Kalee (even/odd)
Kashyyyk (even/odd)
Kril'Dor (even/odd)
Tatooine (even/even)
Vandelhelm (even/even)
Velusia (even/odd)
Yaga Minor (even/even)
You can check your answers for this puzzle on Geochecker.com. Geochecker has been set to allow fuzzy results within 0.005 minutes so that little inaccuracies shouldn't prevent you from getting there. If you think you have it right, but don't get the green light, feel free to send me your planet coordinates and I will let you know if you are close.
Hm, what is it about Fresh Pond that it attracts these kinds of puzzles? See GC14PMP.
Update 12/9/2012: Replaced container with a micro (bring tweezers!) in a slightly different location. From the location confirmed by Geochecker subtract .003 from North and subtract .026 from West to get the new coordinates. Hint has also been updated.
