- The ring systems around Jupiter and Saturn lie outside those planets respective Roche limits. True or false? How do you know?arrow_forwardWhat 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.)arrow_forwardWhat determines which cloud layers are found at which altitudes in Jupiters and Saturns atmospheres?arrow_forward
- What should the interior composition of Titan be if its density is 1.9 g/cm3? How do you know?arrow_forwardThe water clouds believed to be present on Jupiter and Saturn exist at temperatures and pressures similar to those in the clouds of the terrestrial atmosphere. What would it be like to visit such a location on Jupiter or Saturn? In what ways would the environment differ from that in the clouds of Earth?arrow_forwardIf Uranus and Neptune had no satellites at all, would you expect them to have rings? Why or why not?arrow_forward
