The Outer Planets

The Outer Planets

• The four planets farthest from the Sun: Jupiter, Saturn, Uranus, Neptune

• Also called the “gas giants” and the “Jovian planets”

• Larger than the inner planets

• Surfaces are made up of gases

• Separated from the inner planets by an asteroid belt

Pluto is a “dwarf planet.”

JupiterMoons: 62Rings: 1• Axis 3• Fifth planet from the Sun• A gas giant• All other planets could fit into it• Made of mostly 90 % hydrogen

and helium with no solid surface

• Solid Core- Metallic Hydrogen• Atmosphere is cold- -150

degrees Celsius • Its Great Red Spot is bigger

than Earth, 300 Years old• Clouds change color daily• 4 Galilean Moons• 12 years to orbit around the

Sun.

SaturnMoons: 62Rings: thousandsAxis: 27 degrees

• Sixth planet from the Sun• Second-largest planet• Cold atmosphere is made up

of 92 percent hydrogen and 6 percent helium

• -170 degrees Celsius • Has no solid surface• Over 1,000 rings of rocks, dust,

and water ice orbit the planet• Has the most moons of the

planets in our solar system• 29 Years to orbit the Sun.

UranusMoons: 27Rings: 13Axis : 98

• Atmosphere is mostly liquid hydrogen and helium with a small amount of methane

• Third-largest planet• Very thick atmosphere• Very cold -200 degrees Celsius • Giant gas planet• Cold methane gas makes it

look blue-green• Orbits on its side• 84 Years to orbit the Sun.

NeptuneMoons: 13Rings: 9Axis: 30• Atmosphere is mostly liquid

hydrogen and helium with a small amount of methane

• Medium-large planet• Thick atmosphere• Extremely cold -210 degrees

Celsius • Takes 165 Earth-years to orbit

the Sun!
