(6) Moons of Mars.
In 1727, Jonathan Swift wrote Gulliver's Travels in whichhe described two moons orbiting Mars. About 150 years later, theAmerican astronomer Asaph Hall used a large telescope to discovertwo moons of Mars and they were named Phobos (\"fear\") and Diemos(\"terror\"). Their motions were surprisingly close to JonathanSwift's description. The orbital period of Phobos is 8 hours andthat of Diemos about 30 hours.
(2 pts.) (a) Using the information given aboveand one of Kepler's laws (which one?), explain which moon, Phobosor Diemos, is farther from Mars.
(2 pts.) (b) Describe the motions of Phobos andDiemos as seen by an inhabitant of Mars at, say, 40° north martianlatitude.
(Note: Phobos and Diemos both orbit Mars close to Mars'equatorial plane and in the same (counterclockwise) direction thatMars spins. Mars' spin period is close to 24 hours. Drawingdiagrams would probably help).
