But through the Sagan Planet Walk, organized by the Cornell Society of Physics Students, a tour of all the planets is still possible. Each obelisk contains a circular frame with a small hole, the size of which depicts the planet’s size relative to the Sun. A key highlight is the obelisk depicting the asteroid belt, at the base of which is the world’s only unguarded meteorite. In 2015, it was decided that the walk would be expanded to include an obelisk depicting the exoplanet Kepler-37d on the moon, nearly 238,900 miles away, though this is yet to be completed. This was exactly what the event was meant to do, inspire, encourage and excite people about science,” Kruk said.
