  1. The Outer Planets • Ringed, Gas giants except Pluto • No known solid surfaces • Jupiter, Saturn, Uranus, and Neptune. Chapter 16 - 3

  2. Jupiter • 43.3 light minutes or 5 AU from the sun • Temp. -153 degrees C • Gravity: 236% of Earth’s • 62 moons - Io, Europa, Ganymede and Callisto • Revolution: almost 12yrs. • Rotation: almost 10 hours • Atmosphere: • Water, methane, ammonia • Great red spot - permanent storm 3 times the earth’s size

  3. Saturn • 1.3 light hours or 9.54 AU from the sun • Temp. -185 degrees C • Gravity: 107% of Earth’s • 61 moons and most visible rings in the solar system – Titan is Saturn’s largest moon • Revolution: 29 years 155 days • Rotation: 10 hours 39 minutes

  4. Uranus • 2.7 light hours or 19 AU from the sun • Temp. -214 degrees C • Gravity: 91% of Earth’s • 27 known moons - Miranda • Revolution: 83 yrs 272 days • Rotation: 17 hrs. 14 min. retrograde (clockwise) • Tipped over on its side - axis of rotation is almost 98 degrees

  5. Neptune • 4.2 light hours from sun or 30 AU • Temp. -225 degrees C • 13 moons and 5 rings - Triton • Revolution: 163 years, 263 days • Rotation: 16 hrs. 7 min. • The Blue World: -Has a Great Dark Spot -Clouds

  6. Pluto • In 2006 Pluto was reclassified as a dwarf planet. • Different from outer planets - smaller than Earth’s moon and rocky • 5.5 light hours or 39.5 AU (average) from sun • Temp. -235 degrees C • One moon - Charon is more than half Pluto’s size • Revolution: 248 years • Rotation : 6 days 10 hours retrograde • Elliptical orbit brings Pluto closer to the sun than Neptune for a short period of time during its revolution

  7. Mnenomic Device • Eight planets, in order, from the sun outward • Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune • My Very Excellent Mother Just Served Us Noodles
