Sun is scaled one meter (39") in diameter. Actual Size of Sun: 1,391,000 km (864,000 mi) AU (“Astronomical Unit”) is the average distance between the Sun and Earth: 150 million km (93 million mi) A little more than 100 Sun diameters will span the distance of one AU.
Use your large parks to create a TRULY scale model Solar System in both size AND scale, something practically impossible in any other venue. It can be elaborate, like in the above picture from the Peoria Riverfront Museum in IL, or just print out the NASA "Planets to Scale PDF," and find some space.
Make a Scale Model of the Distances in our Solar System. About the Activity. Using a strip of paper, construct a quick scale model of the distances between the orbits of the planets, the Asteroid Belt, and Pluto as part of the Kuiper Belt. Topics Covered. Scaled distances of orbits in the Solar System. Types of objects in the Solar System.
• Talk about what a solar system model that demonstrates the relative average distances between the planets and the Sun and the relative sizes of the planets would look like. Save your Solar System Statistics cards for future activities.
This 2D visual model illustrates the scale of the sun and planets in our solar system, and their current distance from each other.
Although we could print the planet sizes to scale, the paper would need to be way too large to show the scaled distances. Instead, to help you understand the sizes and distances of our solar system, we’ve created a scale model. Our Solar System, real imagery but not to scale.
Download the Scale Size and Distance Spreadsheet (XLSX or CSV) or the Solar System Sizes and Distances reference guide if calculating manually. Decide on the diameter of Earth in your scale model. Keep in mind that a 1-cm Earth means the scale distance from the Sun to Neptune is about two miles.
