why pluto was once thought to be a planet but is no longer considered as one?
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?

Why or why not? O Yes. That is why the outer planets are shown in a separate box. O No. The distances in the solar system are too great to produce a model accurate to distance that still has inner planets visible. O No. The outer planet distances are drawn to scale, but the inner planets need to be drawn farther from the sun to be visible. 1 4arrow_forward
