Unit C: The PlanetsC1: What are the physical and orbital properties of the planets? Go through IntroductionGo through Rocky WorldsQuestion 1c: Why is the third planet from the Sun very different from the others?A: it is the only planet with liquid water on the surfaceQuestionit is the only planet with liquid water on the surfaceQuestion 1g: List several things that all four planets have in common.A: solid surface, terrestrial planets, heavy metal core, rocky mantleGo through Gas GiantsQuestion 2b: Examine Saturn's rings. What evidence shows that the rings are not a solid mass?A: It’s thin and see throughQuestion 2c: If each planet has a thick atmosphere why can't we breathe it?A: because there is not enough oxygen or no oxygen at all for us to breathe it safelyQuestion 2d: Which planet has the shortest day?A: JupiterQuestion 2e: How old are you in "Jupiter years"?A: i would be one years oldGo through RingsEveryone knows that Saturn has a magnificent ring system. But what is not as well known is that Jupiter, Uranus, and Neptune also have several faint rings.Go through PatternsThere are patterns in the solar system. What is the pattern or relationship between the:Question 4a: type of planet and its distance from the Sun?A: terrestrial planets are closer to the sun, and the gas planets are further from the sunQuestion 4b: length of the planet's year and its distance from the Sun?A: the further away a planet is from the sun, the longer the length of the planet’s year will beQuestion 4c: type of planet and its atmosphere?A: terrestrial planets have light gases in their atmospheres and the gas planets have heavy gases in their atmosphere
Question 4d: size of the planet and the number of moons it has?A: the bigger the planets, the more moons it has usually because of its stronger gravityGo through Is That All There Is?Question 5: Do you think any more planets beyond Neptune’s orbit will be discovered? Explain your answer. A: yes, probably because space is so big and we probably just haven't gotten to it yet.SKIP EXTRA CREDIT :) C2: Motion of PlanetsGo through IntroductionGo Through C2-4 What Causes Retrograde Motion? Does Mars really move "backward"?Let's examine a space-based view of the dates in question.Click the Run Time Forward Reset button to watch Mars and the Earth as they orbit the Sun.Question 4a: Which planet moves faster? What is Earth "doing" to Mars? A: Earth moves faster and passes MarsQuestion 4b: Is Mars actually moving "backward" at any time?A: NoClick the Reset Reset button if you wish to see the motion again.Question 4c: What causes retrograde motion?A: The different speeds at which the planets orbit the SunQuestion 4d: In which direction (clockwise or counterclockwise) are Mars and Earth moving?A: ClockwiseQuestion 4e: Do all planets move in that direction?A: Yes they all doClick on the link on Starry Night to find out. Zoom in for a better view of the inner solar system.Go Through C2-5 Extra Credit - NOT Optional - you must answerFor many thousands of years people believed that the Earth was the center of the universe. How would the motion of the Sun and planets appear if everything went around the Earth?Click the Run Time Forward Reset button to set the planets in motion.Extra Credit a: Describe the motion of the Sun and the planets in this Earth-centered view. A: They all do loops but follow where the sun is going; when they do a loop, they turn to follow thesun
Extra Credit b: Describe the motion of the planets in the Sun-centered view of the solar system. A: system.They are just out kind of doing their own thing but they are still following the sun it just doesn't look like it because they are so farC4: Why was Pluto reclassified as a dwarf planet?Go through IntroductionGo Through C4-1 Is Pluto a Planet?Let’s review what we learned about Pluto earlier. The Sky Chart shows the orbits of the outer planets and Pluto as seen from high above the solar system.Question 1a: How does Pluto’s orbit differ from the orbits of the other planets?A: Click to see the orbits edge-on.Question 1b: How else does Pluto’s orbit differ?A: In addition, Pluto’s mass and diameter are much smaller than any other planet in our solar system.In 2006, astronomers decided that Pluto was no longer a planet. It is now called a dwarf planet.Question 1c: Do you think astronomers made a good decision? Why?A: Go Through C4 other sections - reviewing and clicking items only. Answer questions to yourself for these… you do not need to record answers for the other sections.
