Sagan Planet Walk

The Sagan Planet Walk is a walking scale model of the solar system, extending 1.2 km from the center of The Commons in downtown Ithaca, NY, to the Sciencenter, a hands-on museum featuring over 250 exhibits.

The exhibition was created in memory of Ithaca resident and Cornell Professor Carl Sagan by the Sciencenter in 1997. Professor Sagan had been a founding member of the museum's advisory board and was instrumental in developing the institution's educational philosophy.
