If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line at a wavelength of 505 nm, what difference in wavelength (in nm) should you expect between the opposite edges of the rings? (Hints: The radius of the edge of the A ring is 136,500 km. Use the formula for orbital velocity, V. GM and the formula for Doppler shift, -

Neptune is about 50,000 km in diameter, and its largest moon, Triton, is about 2700 km in diameter. If you represent the planet with a ball 10 inches in diameter, how big a ball will you need to represent Triton? Triton orbits 355,000 km from Neptune. How far from Neptune would you place Triton in the model?
Saturns rings are primordial, meaning that they originated when the planet formed. True or false? How do you know?
If Uranus and Neptune had no satellites at all, would you expect them to have rings? Why or why not?
What is the orbital velocity and period of a ring particle at the outer edge of Saturns A ring? (Hint: Use the formula for circular velocity, Eq. 5-1a. The formula requires input quantities in kg and m.) (Note: The radius of the outer edge of the A ring is 136,500 km.)
The Cassini spacecraft recorded the image shown here of Saturns A ring and the Encke Gap. What do you see in this photo that tells you about processes that confine and shape planetary rings?
Why is Saturn’s moon Enceladus such an exciting place to send a mission?
Uranus is about 26,000 km in radius, and its main ring is about 51,000 km from the planets center. If you represent the planet with a ball 5 inches in radius, how far from the center would you place its main ring?
If Jupiter had a satellite the size of our own Moon orbiting outside the orbit of Callisto, what would you predict for the satellites density and surface features?
How does the solar nebula theory explain the significant density difference between the Terrestrial and Jovian planets?
How are the atmospheres of Earth and Triton similar?
What is the maximum angular diameter of the dwarf planet Ceres when it is closest to Earth? Could Earth-based telescopes detect surface features? Could the Hubble Space Telescope? (Hint: Use the small-angle formula, Eq. 3-1.) (Notes: Ceress average distance from the Sun is 2.8 AU and its diameter is 950 km. The best angular resolution of Earth-based telescopes at visual wavelengths is about 1 arc second and of Hubble about 0.1 arc second.)
