I would like you to compare the size of some of the largest moons of the solar system to their host planets. Using diameters of 12,700 km, and 140,000 km, 116,000 km for Earth, Jupiter, and Saturn respectively, please provide the ratios of the following moons to their host planets (you can use Table 12.1 from the book to get the diameters of the moons): Luna (Earth's moon), Io, Callisto, Ganymede, Europa, and Titan. After collecting those ratios, please tell me one thing that you notice that stands out about those results.
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_forwardWhat is the range of density for the outer planets (in g/cm3)? 1.2 to 5.5 2.2 to 5.5 2.2 to 6.5 3.3 to 7.2 none of thesearrow_forward
