Our Solar System – Size and Scale

Go online and find the diameter and distance from the sun for the following objects in our solar system and beyond. You can find this information at or a number of other reputable sites. Make sure you keep the units the same so that you can calculate the percent of the distance to Pluto. Our model will represent our solar system by scaling it down to 100 meters (or 0.1 km).
