About Lesson 11

Artist's diagram of the planets in our solar system
Figure 11.1: "Our solar system features eight planets, seen in this artist's diagram....This representation is intentionally fanciful, as the planets are depicted far closer together than they really are. Similarly, the bodies' relative sizes are inaccurate. This is done for the purpose of being able to depict the solar system and still represent the bodies with some detail. (Otherwise the Sun would be a mere speck, and the planets -even the majestic Jupiter-would be far too small to be seen.)"

By the end of Lesson 11, you should be able to:

  • compare and contrast the interior structure and atmospheres of Mercury, Venus, Earth, and Mars;
  • qualitatively describe the process of tidal locking and relate this phenomenon to Mercury’s orbit around the Sun and the Moon’s orbit around the Earth;
  • describe the role impacts and collisions had on the evolution of the Inner Solar System planets and the Moon;
  • compare and contrast the terrestrial planets and the Jovian planets;
  • describe the processes for the formation and evolution of ring systems around giant planets;
  • compare and contrast the moons of the Jovian planets;
  • relate the appearance of the Jovian planets to atmospheric processes;
  • describe the relationship between Pluto and the Kuiper Belt;
  • explain the origin of comets and their distribution in the Solar System;
  • describe the process by which a “shooting star” appears in the night sky.
