Sagan Planet Walk
The Sagan Planet Walk is a walkable scale model of the solar system, located in Ithaca, New York. The model scales the entire solar system—both planet size and distances between them—down to one five billionth of its actual size. Consisting of 11 obelisks situated along a path through the streets of downtown Ithaca, the Planet Walk leads from the sun at Center Ithaca to Pluto at the Ithaca Sciencenter.
The exhibition was originally created in 1997 in memory of Ithaca resident and Cornell Professor Carl Sagan.〔(【引用サイトリンク】url=http://www.sciencenter.org/SaganPW/ )〕 In 2012, the model was expanded to include a representation of the sun's closest neighboring star--Alpha Centauri—at the ‘Imiloa Astronomy Center at the University of Hawaii, making it the world's largest exhibition. In 2014 the inner planets and sun were removed as part of extensive construction being done to the Ithaca Commons, but have since been replaced.
==Individual models==
The scaled size of the sun is given by a diameter circular frame repeated at the top of each tall obelisk. Centered within each sun-sized frame, the proportional size of each planet is represented by a small sphere affixed in a glass window. All of the original planet locations were chosen not only for accuracy to scale but also to highlight local landmarks and public spaces within Ithaca. However, since the original installation of the Planet Walk the public library has moved to a new location, leaving Saturn no longer attached to a local landmark.
