  3. Numerical Questions

  4. Numerical Questions • A minor planet, orbiting the Sun, has a semi-major axis of 4 AU. What is its period? • If the middle of the Oort cloud is 20,000 AU away, how long does it take light from there to reach us? • A rover on Mars, which we assume is 0.6 AU from Earth, will go over a cliff in 6 minutes 10 s unless a radio signal reaches it in time to stop it. Is it worth sending a signal?

  5. General Knowledge

  6. Time and Lunar Phases • If the full Moon is high in the sky, what time is it approximately? 6am Sun Earth Full Moon New Moon Noon Midnight 6pm
