Chapter 16-19 Review
  • We’ve covered this material fast – exam will not cover subtle concepts or obscure facts.  Very basic information and only the most fundamental ideas.
  • Things you should know include:
    • Order of planets in solar system, general sizes of orbits, sizes and compositions of the planets (also asteroids and comets in general, notable moons).
    • How these items fit into the solar nebula picture.

Chapter 16: Origin of the Solar System
  • Solar Nebula Hypothesis
    • Context for Understanding Solar System
  • Extrasolar Planets
    • Dust Disks, Doppler Shifts, Transits and Eclipses
  • Survey of the Solar System
    • Terrestrial Planets
    • Jovian Planets
    • Other “Stuff” including apparent patterns with application to the nebular hypothesis
5
Chapter 17: Terrestrial Planets
  • Comparative Planetology
    • Earth
      • History, Interior, Crust, Atmosphere
    • The Moon
      • In particular origin
    • Mercury
    • Venus
    • Mars
      • Including water (and life ?)
6
Chapter 18: Worlds of the Outer Solar System
  • Jupiter
      • Condensation model (Ice and Velcro effect)
      • Atmospheric winds
      • Atmospheric chemistry
      • Magnetic fields
    • Other Jovian Planets (Saturn, Uranus, Neptune)
      • will only cover major differences from Jupiter
    • Satellites (i.e. Moons)

Ch. 19:  Meteorites, Asteroids, Comets
  • Small bodies, not geologically active
  • “Fossil” record of early solar system
    • Asteroids
      • Mostly from region between Mars and Jupiter
      • Left over small debris from accretion, never assembled into a large planet
      • Meteorites come mostly from asteroids
    • Comets
      • “Stored” on large elliptical orbits beyond planets
      • Thought to be “planetesimals” from Jovian planet region, almost ejected from solar system in its early history
      • Brought water to earth, cause meteor showers
  • Meteorites are “asteroids” fallen to Earth
  • Pluto, Kuiper Belt Objects

Chapter 16-19 Review
  • Example questions:
  • Multiple choice:
    • On a photograph of the moon, the moon measures 30 cm in diameter and a small crater measures 0.2 cm.  The moon’s physical diameter is 1738 km.  What is the physical diameter of the small crater?
      • About 1738 km
      • About 12 km
      • About 520 km
      • About 350 km
      • About 3.5 km
