Homework Set 6
DUE: Friday, June 28



Some of these questions entail looking up concepts and numbers in the book and in the Handout 3, "Does Titan Have Oceans?". In your book, you will have to look in Ch 5 for temperature scales. Please use a separate piece of paper for your answers.


1. How far are each of the Galilean satellites from Jupiter, in kilometers? How many times further are each of them from Jupiter, compared with the distance between the Earth and the Moon?


2. Imagine that you are in a spacecraft above the south pole of Jupiter. Draw Jupiter, it's rings, the 4 inner most satellites, the Galilean satellites, and the 8 smaller outer satellites. Label the Galilean satellites correctly, and draw the direction around Jupiter in which each of the satellites moves. Also draw the rotation of Jupiter.


3. Does Jupiter exhibit retrograde motion in the sky? If so, is its retrograde loop bigger, smaller, or the same size as Mars? Why?


4. Saturn's rings should naturally spread apart, some of them falling in towards Saturn, and some of them drifting out into space. Why don't they do this? Please be precise with your answer. Hint: it has something to do with moons.


5. At what temperature do methane-nitrogen clouds form in Titan's atmosphere? Please give your answer in Centigrade, Fahrenheit, and Kelvins. What height above Titan's surface is this?


6. What is the height of the top of the ethane-acetylene haze layer above Titan? What is the temperature there, in Celsius, Fahrenheit, and Kelvins?
