Some astronomers argue that Jupiter and Saturn areunusual, while other astronomers argue that all solarsystems should contain one or two such giant planets.
You are making a scale model to visualize the relative sizes of the planets in our solar system. The scale of the model is: 1 cm = 2000 km. The radius of Saturn is 60,000 km. At what radius will Saturn appear on your scale model?
