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

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: years, 263 days Rotation: 16 hrs. 7 min. The Blue World: Has a Great Dark Spot -Clouds

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 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
