Outer Planet review 1) Much of what we know about the outer planets comes from information gathered by what spacecraft? Voyager 2) Jupiter’s giant red spot is actually a large storm. 3 times larger than the earth. 3) What minefield lies outside of the orbit of mars and presents a large obstacle for travelling to the outer solar system? Asteroid belt 4) How does the composition of outer planets differ from that of the inner planets? Inner planets are rocky, outer planets are comprised of overwhelmingly gas 5) What are the names of Jupiter’s (large) moons? Io, Europa, Ganymede, Calisto 6) What are incomplete planetary rings, similar to those around Neptune, called? Ring Arcs 7) Where does Jupiter’s name come from? Roman god, (Zeus) King of all gods 8) Who first proposed the presence of Neptune and why? Scientists predicted its presence based on calculations made on Uranus’ orbit 9) Uranus’ axis is roughly 90 degrees different than the rest of the planets. What does this mean for the change of “seasons” on Uranus? Much more extreme. No night during summer, no day during winter. 10) If Jupiter’s magnetosphere were visible how large would it appear in our sky? Bigger than the sun, even though it is 5 times further away. 11) What term is given to the amount of light reflected off of a planet? Albedo 12) What is the currently most widely accepted theory concerning the origin of Saturn’s ring? A former moon was destroyed and lies in small pieces around the planet 13) Why is Uranus blueish-green? Large amounts of methane, which reflects light in the blue green range 14) Do Uranus and Neptune have rings? Yes, at least partial rings, Called ring arcs. 15) What is significant about the discovery of Uranus? First planet discovered with a telescope 16) Triton, the solar system’s largest moon, is special because: It is larger than pluto, it is the coldest object observed, it orbits in a direction opposite of almost everything else in the solar system 17) What is the heat source that drives the winds on Neptune? Geologic heat 18) How is Pluto’s orbit different from other planets? Not on the same plane and very eccentric 19) Does Pluto have an atmosphere? Seasonal. At times during its orbit it is close enough to the sun for some of the gases to sublime and form a temporary atmosphere.
