Planet Walk

Our solar system is truly grand—nearly 6 billion miles from the sun to the orbit of the dwarf planet Eris! The Planet Walk, a 5.5-mile journey, starts outside Impression 5 Science Center, winds along the River Trail and ends at Abrams Planetarium on Michigan State University's campus. Enjoy a beautiful stroll and, with each footstep demonstrating one million miles, experience a scaled representation of our solar system!
