Chapter 14: Problem 52
Search the World Wide Web for a list of trans-Neptunian objects. What are the largest and smallest objects of this sort that have so far been found, and how large are they? Have any objects larger than Eris been found?

Get started for freeBriefly describe the evidence supporting the idea that Uranus was struck by a large planetlike object several billion years ago.
Explain the statement "Methane is to Uranus's atmosphere as water is to Earth's atmosphere."
Use the Stary Night Enthusiast \({ }^{\text {TM }}\) program to observe the five large satellites of Uranus. Open the Favourites pane and click on Guides \(>\) Atlas to display the entire celestial sphere. Open the Find pane and double- click the entry for Uranus to center this planet in the view. (Clicking once on the Space bar will speed up this centering). You can reduce the confusion in this view by removing the background stars by clicking on View \(>\) Stars \(>\) Stars and by ensuring that the celestial grid is removed by clicking on View > Celestial Grid. Using the controls at the right-hand end of the toolbar, zoom in to a field of view of about \(2^{\prime} \times 1^{\prime}\). In the toolbar, set the year to 1986 and the Time Flow Rate to 1 hour. Then click on the Run Time Forward button, the right-pointing triangle on the toolbar. You can scroll on and off the labels for the moons by clicking on Labels > Planets-Moons. (a) Describe how the satellites move, and relate your observations to Kepler's third law (see Sections 4-4 and 4-7). (b) Set the year to 2007 and again click on the Run Time Forward button. How do the orbits look different than in (a)? Explain any differences.
(a) Find the semimajor axis of the orbit of an object whose period is \(3 / 2\) of the orbital period of Neptune. How does your result compare to the semimajor axis of Pluto's orbit? (b) A number of Kuiper belt objects called plutinos have been discovered with the same orbital period and hence the same semimajor axis as Pluto. Explain how these objects can avoid colliding with Pluto.
How does the energy source for Uranus's atmospheric motions differ from those from Jupiter, Saturn, and Neptune?
