The Lethbridge Solar System Model
About This Project Our Solar System is vast, with huge distances between the planets. Light from the Sun (traveling at 300,000 km per second) takes more than eight minutes to reach the Earth, and more than four hours to reach Neptune. Such large numbers and enormous distances are difficult to imagine, and hard to relate to our day-to-day lives. This project brings our Solar System “down to Earth”, and centers it on the city of Lethbridge. It gives us a sense of the Solar System’s enormity and highlights some special features of each planet. |
The Sun is represented by the 5.5-meter diameter dome atop the clock tower of Lethbridge’s Post building. Each planet model is sized true-to-scale in relation to the 5.5-meter “Sun”, and placed somewhere along its pathway around the Sun. Each pedestal carries a descriptive plaque with basic facts about the planet, and a QR code that links to our website for more information.
The scale ratio is 1:254,000,000. If we scale the speed of light by the same ratio, it would travel about 1.2 meters per second. So, within our Solar System Model, light would travel at about walking speed- something to think about as you stroll from one exhibit to the next. |
Enjoy your journey through our Solar System! We hope you learn new things, and that these installations will encourage you to learn more about our Solar System and our Universe. As you visit each planet, don’t forget to look around you! The installations are near local points of interest- the Cenotaph at City Hall, the Galt Museum and Archives, and the University of Lethbridge to name just a few.
