B.I Solar System Geocache Hunt
Discover Bainbridge Island Parks with your family while travelling through our scaled solar system model.
Welcome to the Washington State’s only solar system geocache, scaled to a 5 foot Sun, located on Bainbridge Island! Below you will find fun facts about our model solar system, as well as the GPS coordinates of each planet, including Pluto. When you collect stamps from each location you can turn in a finished passport book for a fun finisher patch to iron onto your backpack, jacket, or wherever your imagination takes you!
Current Conditions of the Hunt
Neptune is completely missing. Maintenance is planned to replace these items, as well as replace the plastic treasure chests with cloth zip bags.
Updates planned for 6/21/17
Bainbridge’s scaled solar system model is based on a 5-foot wide sun. This is about a 1:1,000,000,000 scale model – what would the other planets look like if they were scaled down the same way?
Mercury would be a typical LED.
Venus would be a small marble.
Earth would be a dime. (If the moon were in our model, it would be a mere foot away!)
Mars would be a wooden bead.
Jupiter would be a dollar bill.
Saturn would be a DVD.
Uranus would be a pool ball.
Neptune would be a pool ball.
Pluto would be two pinheads.
Planet 9* would be slightly smaller than a pool ball.
Getting to Bainbridge Island:
From Seattle you can take the WADOT ferry to Bainbridge Island. The Sun and inner planets are walkable from the ferry. Jupiter and Saturn can be walked from the ferry terminal with a bit of extra effort. Uranus, Neptune, and Pluto will require a car.
From Kitsap County you can drive across the Agate pass bridge onto Bainbridge Island and follow highway 305 into the town center where the Sun resides.
