Solar System to Scale Hike

Solar System to Scale Hike at San Bruno Mountain

Updated Tuesday, March 12, 2021

Ever wish you could travel to the Moon and back? What about to Neptune?

Our solar system is larger than the eye can see, but not farther than you can hike with our newest exhibit: Solar System to Scale in San Bruno Mountain Park.

Walk from the sun to the eight planets in its orbit with educational panels about each planet along the way in this Solar System that is 670 million times smaller than in space!

This exhibit, originally a celebration of National Astronomy Week in November 2020, will run for several more months. The Solar System Route is also the route of the Take A Hike Challenge.

Check out this great website that allows you to travel the solar system at scale.
