Textbook Question
Chapter 8, Problem 39EAP
Comparing Jovian Planets. You can do comparative planetology armed only with telescopes and an understanding of gravity.
- The small moon Amalthea orbits Jupiter at about the same distance in kilometers as Mimas orbits Saturn, yet Mimas takes almost tvlice as long to orbit. From this observation, what can you conclude about how Jupiter and Saturn differ? Explain.
- Jupiter and Saturn are not very different in radius. When you combine this information with your answer to part (a}, what can you conclude? Explain.

Imagine a trans-Neptunian object with roughly the same mass as Earth but located 50 AU from the sun. a) based on the solar nebula theory, what do you think this object would be made of and why? b) on the basis of speculation, assume a reasonable density for this object and calculate its diameter in units of Earth radii.
Compare Titan to Rhea. Estimate the strength of surface gravity on Titan compared to the gravity on Titan. How does this affect the possibility of an atmosphere on each?
Use g=GM/R2
Titan Radius: 2,575 km, Mass: 2.31 x 1021 kg
Rhea Radius: 764 km, Mass: 1.35 x 1023 kg
Density is mass per unit volume. Granite rock weighs about 2.7 g/cm3, water weighs about 1.0 g/cm3. Knowing their sizes, how might you determine whether Europa or Ganymede is hiding a large liquid water ocean beneath an icy crust?

- How does the solar nebula theory explain the orbits of the major planets? Dwarf planets? Does it explain the rotations of the planets? Why or why not?arrow_forwardWe have a lot of good images of the large moons of Jupiter and Saturn from the Galileo and Cassini spacecraft missions (check out NASA’s Planetary Photojournal site, at http://photojournal.jpl.nasa.gov, to see the variety). Now that the New Horizons mission has gone to Pluto, why don’t we have as many good images of all sides of Pluto and Charon?arrow_forwardWhat is the maximum angular diameter of Jupiter as seen from Earth? Repeat this calculation for Neptune. Relevant data can be found in Celestial Profiles 7 and 10. (Hint: Use the small-angle formula in Reasoning with Numbers 3-1.)arrow_forward
- Which step(s) listed in the previous question can be eliminated in models that form Jovian planets in thousands of years, a time frame that solves the Jovian problem? Order the following steps in the formation of a Terrestrial planet chronologically: gravitational collapse, accretion, outgassing, condensation, and differentiation.arrow_forwardCompare the interior cutaway sketches of the four Jovian planets in their Celestial Profiles. What interior layer(s) is (are) shown in Jupiter and Saturn but not in Uranus and Neptune, and vice versa?arrow_forwardPresent theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. So how can we explain the presence of jovian-sized exoplanets closer to their star than Mercury is to our Sun?arrow_forward
- What is the smallest-diameter crater you can identify in the photo of Mercury in Figure 2 of the Concept Art: Terrestrial and Jovian Planets? (Hint: See Appendix Table A-10, Properties of the Planets, to find the radius of Mercury in kilometers for scale.)arrow_forwardCalculate the radius of Jupiters Roche limit for a satellite with density equal to the planet. Which of Jupiters moons is closest to the Roche limit? What might that tell you about the relationship between that moon and Jupiters ring? (Note: Necessary data are given in Celestial Profile: Jupiter and Appendix Table A-11.)arrow_forwardHow does the solar nebula theory explain the significant density difference between the Terrestrial and Jovian planets?arrow_forward
- I would like you to compare the thickness of Saturn's rings to objects here on Earth if those rings were scaled down to the size of the objects here on Earth (hint: this means it is a ratio problem). Imagine the rings of Saturn like a DVD or CD here on Earth. The DVD has a diameter of approximately 12 cm, whereas the rings of Saturn have a diameter of approximately 280,000 km. The thickness of a DVD is about 0.6 mm and the thickness of the rings of Saturn at their thickest is approximately 1 km. If we were to scale the diameter of rings of Saturn down to the diameter of a DVD, how does the new thickness of the rings of Saturn compare to the thickness of the DVD? Please provide both the new thickness of Saturn's rings and how many times thicker or thinner they would be than a CD in your answer.arrow_forwardHow do terrestrial and giant planets differ?
