Celestial Bodies in the Solar System - Chapter Summary

This chapter's lessons look at the structures in our solar system, their origins and how they move. You'll examine an overview of planetary geology and review information on the inner and outer planets, including their important characteristics and what they're made of. You'll look at the origins and properties of meteorites, meteoroids, asteroids and comets. By the time you've watched all these lessons, you should be able to:

  • Discuss the characteristics of the planets in our solar system
  • Share information about how satellites are formed
  • Describe the classifications and characteristics of meteorites
  • Examine the origin and orbits of meteoroids
  • Give information on the origins and properties of asteroids and comets
  • Relate facts about the dwarf planets of Pluto, Eris, Haumea and Ceres

These brief video lessons are available anytime on a computer or mobile device. Video tags make it easy to return to the lesson to review key points. At the end of every lesson is a multiple-choice quiz that lets you assess your knowledge of the topics covered.
