The fantastic Exploratorium Museum of Science, Art, and Human Expression in San Francisco, California has a fun little app on their website that shows you your age and when your birthday is on other planets of our solar system.
So now, utilizing this glorious tool, you can have your Martian, Venusian, or Plutonian (nertz to you Neil deGrasse Tyson!! My son may not putting it on his galaxy-mobiles, but by gosh, I’ll always have the 9th planet in my heart!) birthdays!
You can even have a theme party! Since Mercury goes so fast, you can have a couple Mercurian Birthdays per year and have everyone wear silver!
So by all means start planning your next planetary birthday party by clicking here and if you’re in San Francisco (or plan to be) by all means, stop by the Exploratorium! For that matter, take a day and support what ever museums may be in your area!
