27 27.1 The Inner Planets The Planets and the Solar System
CHAPTER The Planets and the Solar System CHAPTER HOME 27.1 The Inner Planets VOCABULARY The planets are grouped by position as inner or outer, and by properties as terrestrial or Jovian. inner planets outer planets The inner planets are Mercury, Venus, Earth, and Mars. They are all terrestrial: they have rocky crusts, dense mantle layers, and very dense cores. Mercury Venus Earth Mars Asteroid Belt The Inner Planets SECTION OUTLINE

CHAPTER The Planets and the Solar System CHAPTER HOME 27.2 The Outer Planets The Jovian, or outer, planets are large, consist mostly of gases, and are surrounded by ring systems and many moons. They are Jupiter, Saturn, Uranus, and Neptune. Asteroid Belt Jupiter Saturn Uranus Neptune Pluto The Outer Planets Pluto is too small to be a Jovian planet and not dense enough to be a terrestrial planet. SECTION OUTLINE

27 27.3 Planetary Satellites The Planets and the Solar System
CHAPTER The Planets and the Solar System CHAPTER HOME 27.3 Planetary Satellites A planetary satellite or moon is a smaller body that revolves around a planet. Except for Venus and Mercury, each planet has at least one satellite. Jupiter’s four largest moons, Io, Europa, Ganymede, and Callisto, have yielded some surprising discoveries, such as ice covering Europa and volcanoes on Io.
