Sagan Planet Walk is a walkable scale model of the solar system. The model scales the entire solar system—both planet size and distances between them.
The walk which begins with the Sun station at the downtown Ithaca Commons and ends at the station representing the dwarf planet, Pluto, is 3/4 mile long and includes a free cell phone audio tour narrated by Bill Nye, the Science Guy.
