- We believe that chains of comet fragments like Comet Shoemaker-Levy 9’s have collided not only with the jovian planets, but occasionally with their moons. What sort of features would you look for on the outer planet moons to find evidence of such collisions? (As an extra bonus, can you find any images of such features on a moon like Callisto? You can use an online site of planetary images, such as the Planetary Photojournal, at photojournal.jpl.nasa.gov.)arrow_forwardDoes Titan experience volcanism today? Impact cratering?

- Explain why the planet Venus is differentiated, but asteroid Fraknoi, a very boring and small member of the asteroid belt, is not.arrow_forwardHellas Planitia includes the word "planitia" which is the latin word for "plain" in its name. The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that. The most probable reason for this discrepancy in its name is because: a. It is a simple naming error that for some reason has so far escaped correction. b. There is a disagreement among astronomers about the true nature of Hellas Planitia. c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes. d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.arrow_forwardWhat is the angular diameter of Saturn (in degrees) as seen from the surface of Hyperion?

- In 2015, researchers concluded that Enceladus's subsurface ocean is probably global, instead of just being restricted to the south polar region. What had the Cassini spacecraft found, that led them to their conclusion? a Enceladus wobbles slightly as it orbits Saturn, more so than it could if its ice shell were mostly frozen to the rocky interior. b Enceladus is absorbing so much water (which is ejected by Saturn from its atmosphere) that there must be a global ocean under its icy surface. c The number of large, lava-spewing volcanoes on Enceladus's surface is so high that they can only be the result of liquid water under the whole surface. d The magnetic field of Enceladus is so strong that it can only be explained by a global ocean of salty water under the surface.arrow_forwardEnceladus is a moon of Saturn. What unique feature does it possess? which is the correct answer? Cryovolcanism, where water erupts instead of silicate rock A dense system of rings An atmosphere thicker than Earth's Internal heating due to radioactivity Has an orbit inside Saturn's ringsarrow_forwardIf you visited a planet in another solar system and discovered that it was heavily cratered, but its small moon was nearly crater free, why would that be a surprise?

- How close is Charon to Pluto's Roche limit?arrow_forwardPlanetary scientists are excited about the possibility that some of the moons in the outer solar system might have a global subsurface ocean of liquid water. It's uncertain whether or not Jupiter's moon Callisto has a subsurface ocean, but some scientists think it might. Let's imagine that a short distance below the surface, Callisto has a water layer 20,000 meters thick. Callisto has a radius of 2.410x106 meters. Earth has a radius of 6.378x106 meters, and its oceans are equivalent to a layer of water 3000 meters thick all over the surface of the planet. Which of the following is an accurate comparison of the Earth’s amount of liquid water with this estimate of the amount of water Callisto might have? Group of answer choices If this scenario is correct, Earth and Callisto have roughly the same amount of liquid water. If these scientists are right, Callisto has about one-sixth as much liquid water as the Earth does. If these scientists are right, Callisto has about 11 times as…arrow_forwardThe surface of medium-sized moons provides us with information about the outer solar system.
