Homework, October 26, 2006 AST110-6 Due Date: Tuesday, November 2, 2006 1. Chapter 8. Review Question 1. Briefly describe how the differences in composition among the jovian planets can be traced to their formation in the solar nebula. 2. Chapter 8. Review Question 5. Briefly describe Jupiter’s cloud layers. How do the cloud layers help explain Jupiter’s colors? Why are Saturn’s colors more subdued? Why are Uranus and Neptune blue? 3. Chapter 8, Problem 22. The Importance of Rotation. Suppose the material that formed Jupiter came together without any rotation so that no ‘jovian nebula’ formed and the planet today wasn’t spinning. How else would the jovian system be different? Think of as many effects as you can, and explain each in a sentence. 4. Chapter 8, Problem 23. Minor Ingredients Matter. Suppose the jovian planet atmospheres were composed only of hydrogen and helium, with no hydrogen compounds at all. How would the atmospheres be different in terms of clouds, color, and weather? Explain. 5. Chapter 8, Problem 24. Hot Jupiters. Many of the newly discovered planets orbiting other stars are more massive than Jupiter but orbit much closer to their stars. Assuming that they would be Jupiter-like if they orbited at a greater distance from their star, how would you expect these new planets to differ from the jovian planets of our solar system? How would you expect their moons to differ? Explain.
