Discover more about Colorado Scale Model of the Solar System, CU Boulder

The Colorado Scale Model Solar System, located at the University of Colorado Boulder, offers an engaging and educational experience for all ages. This outdoor exhibit depicts the Sun, the planets, and the distances between them all on a scale of 1 to 10 billion. The model begins outside the Fiske Planetarium with the Sun, about the size of a grapefruit. As you walk along the path, you'll encounter each planet represented proportionally to its distance from the Sun, complete with informative plaques. The inner planets, like Earth (the size of a ballpoint pen tip), are relatively close to the Sun, while the outer planets, like Jupiter (the size of a marble), are much farther apart. The model stretches for about a third of a mile, ending with the dwarf planet Pluto. This provides a tangible understanding of the immense scale of our solar system. Originally dedicated in 1987 to the memory of the Challenger astronauts, including CU Boulder alumnus Ellison S. Onizuka, the model was updated in 2021 as the first installation of a Voyage Mark II model. The updated model also commemorates the Columbia crew, including CU Boulder alumna Dr. Kalpana Chawla. Enhance your visit with the Wanderers CU mobile app, which provides a responsive sound experience triggered by GPS as you move through the model.
