CINCINNATI SIGHTSEEING TOUR FIELD GUIDE
A One-Hour, 450-Foot Walk from the Sun to Pluto — Each Step = 8.2 Million Miles
A guided Planet Walk by the Cincinnati Observatory that scales the solar system across a mapped route so visitors can grasp planetary distances in a single hour.
A One-Hour, 450-Foot Walk from the Sun to Pluto — Each Step = 8.2 Million Miles.
On the Cincinnati Observatory’s Planet Walk, visitors set out from a marked Sun and follow a linear scale model of the solar system: each footstep stands in for 8.2 million miles as guides lead groups through the inner planets, onward past the gas giants and finally to a 450-foot endpoint at Pluto. The program is presented as a guided, immersive way to apprehend the staggering distances between worlds in a compact, walkable tour.

Step-by-Step Solar Distances
The tour uses a consistent scale: each step participants take represents 8.2 million miles, a simple physical metric that transforms abstract astronomical distances into a human-paced progression.
From the Sun Through Inner Planets
Starting at a Sun marker, the walk moves through representations of the inner planets before pushing outward toward the gas giants, giving guests a sense of relative spacing and scale across contrasting planetary zones.
A 450-Foot Trek to Pluto
The scaled journey culminates in a 450-foot walk to the Pluto marker, a compact but evocative finale that crystallizes how vast the outer reaches of the solar system are compared with the crowded inner system.
What the day feels like
What the Planet Walk Feels Like
The tour unfolds as a paced, interpretive walk: guides lead participants from the Sun marker through successive planetary markers so each stop becomes a brief lesson in scale and order. The experience compresses interplanetary distances into an hour-long, linear route that ends at a distant Pluto marker after a final 450-foot segment.
