Our largest exhibit! Start your scale-model journey from the sculpture of the Sun in
Science Park. As you journey along the Planet Walk you will encounter the inner planets (Mercury first, then Venus, the Earth, and Mars), then the outer planets (Jupiter, Saturn, Uranus, and Neptune). To reach tiny Pluto, be prepared for a 1.6-mile walk along the Ridge Trail and Hazen Trail! The distances are scaled to the sizes of the planet models; it's surprising how far apart the planets are, compared to what we expect from pictures of the solar system that we!ve seen in books.
