For most, travelling to the outer reaches of the solar system is a distant dream. But through the Sagan Planet Walk, organized by the Cornell Society of Physics Students, a tour of all the planets is still possible. The event, attended by over a 100 Ithacans, took place on Saturday. The walk follows 11 monolithic pillars placed along a 0.73 mile path, beginning with one depicting the Sun in the center of the Ithaca Commons and ends with Pluto at Ithaca Sciencenter. Each obelisk contains a circular frame with a small hole, the size of which depicts the planet’s size relative to the Sun.
