Learn about placement of the planets in relationship to the sun and moon in a practical way. This 1.8-mile Scale Model 1:2,000,000,000 Walking Tour of Our Solar System (one of only five in the United States) takes visitors from the sun at the Southeast corner of the Historic Downtown Square (near the courthouse) and ends just past the tennis courts and American flag, where you will come to Pluto and Alpha Centauri. For a copy of the brochure that contains descriptions of planets and an informative and directional map, call the Gainesville Tourism Office at 770-531-2664 or 770-531-6598.
