You have reached Venus in the Plant Trek

Dane County

In our scale model, Venus would be the size of a peach.

What is Planet Trek Dane County?
Welcome to Venus within Planet Trek Dane County! You're now part of a scale model of our solar system centered near Monona terrace in Madison. In this model, we shrink the sun to a sphere about 24 feet in diameter and shrink all other sizes and distances by the same factor (which is about 200 million to one). At this scale a person walking normally is moving at about the speed of light. This is one of ll stops along the trail to Mt. Horeb, home of Pluto. We designed Planet Trek Dane County to help you visualize the vast scale of our solar system. So whether you're headed in towards the sun or out towards the edge, we're glad you passed for a moment to contemplate the immensity of our home star system. Have a great trek!

Venus is very similar in size and composition to Earth. Its dense atmosphere and proximity to the Sun make its surface the hottest in the Solar System.

Dane County Planet Trek Scale Model Solar System
Planet Trek Dane County (PTDC) was constructed in April 2009 as a celebration of the International Year of Astronomy by UW Space Place and partners. PTDC is an installation uniting science education, art, and outdoor recreation. PTDC is, at heart, a scale model of our solar system: We shrunk the Sun, planets, and other bodies by the same factor so that the sizes and distances are represented to scale relative to each other. In our model, the scale is about 200 million to 1. This means the Sun is a sphere about 24 feet in diameter at Monona Terrace, and Pluto the size of a marble in Mt. Horeb.


That's beautiful Lake Monona visible to the right.

The marker is located in Madison, Wisconsin.
