E) Answer the following questions. Recall that Pluto is now a dwarf planet, and no longer one of the outer planets of the solar system. 1. Compare the diameter of the smallest Jovian planet to the largest Terrestrial Planet. Express this quantitatively (e.g. as a percentage, or ratio). Smallest Jovian Planet: Neptune 4.95e4 Largest Terrestrial Planet: Earth 1.28e4 Earth’s diameter is 25.86% of Neptune’s. 2. How does mass of the planets vary with distance from the Sun? In general, the farther you get away from the sun, the more the planet’s mass is. 3. How does density of the planets vary with distance from the Sun? In general, the farther you get away from the sun, the less the density of the planet is. 4. Explain why mass and density of the planets vary with distance from the Sun. Recall our discussion of the Nebular Hypothesis and pay particular attention to the solar winds during the early stages of the solar system, the thermal gradient across the solar system, and the materials (volatile vs. refractory) that compose the planets.
