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.”

Jupiter Moons: 62 Rings: 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 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.

Saturn Moons: 62 Rings: thousands Axis: 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.

Uranus Moons: 27 Rings: 13 Axis : 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.

Neptune Moons: 13 Rings: 9 Axis: 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!
