UAF Planet Walk Start (Sun)

About this museum

In Fairbanks, Alaska, the University of Alaska Fairbanks has created something genuinely ingenious for a community that spends half the year in profound cold and darkness: an outdoor walk of the solar system scaled to the actual dimensions of interplanetary space. The UAF Planet Walk begins at the Sun station on campus and extends outward through the university grounds, with each planet represented at its correct proportional distance from the Sun. By the time you reach the outer planets, you have walked the equivalent of billions of compressed miles - and the experience makes the emptiness of the solar system something your body knows rather than merely your mind.The experience is disorienting in the best possible way. We understand intellectually that the solar system is mostly empty space, but actually walking it - feeling the distance between stations grow longer and the model planets grow smaller as you move outward past Mars, Jupiter, Saturn, and into the cold reaches beyond - makes that emptiness physical and intuitive in a way that no diagram can replicate. By the time you reach Neptune, the Sun station behind you has shrunk to an almost invisible point. The scale of the cosmos, so difficult to grasp in the abstract, becomes suddenly and vividly comprehensible.Fairbanks is a city where the sky itself is a spectacle - northern lights in winter, midnight sun in summer - and the Planet Walk fits naturally into a broader culture of looking outward and upward. The walk functions across all seasons, and each atmospheric condition offers a different kind of encounter: crisp subarctic air in winter, long golden light in summer, the particular silence of an interior Alaska afternoon.The Planet Walk is accessible 24 hours a day, seven days a week. Admission is completely free. The Geophysical Institute, which oversees the educational outreach program, provides maps and interpretive materials at gi.alaska.edu. For anyone visiting Fairbanks, the Planet Walk is a uniquely Alaskan scientific adventure that costs nothing but an afternoon and rewards you with a new sense of your place in the universe.
