The Outer Planets
The four planets furthest from the sun are the outer planets.
They are . . .large.made of gases.made of mostly hydrogen and helium.have rings.thought to have partly solid cores.

Jupiter
The Outer Planets
Most massive planet. Similar to a star in its composition –
hydrogen and helium. Jupiter’s Atmosphere:
atmosphere with colorful bands and thick clouds.
great red spot is a large, ongoing storm many times larger than Earth.

The Outer Planets Jupiter’s Moons:
Four very large moons.○ Io – most volcanically active body in
solar system and has tides in its solid matter because of Jupiter’s strong gravity
○ Europa – surface is mostly covered with water
○ Ganymede – largest moon in the solar system (larger than Mercury) and only one with its own magnetic field
○ Callistos – lots of craters

Saturn
The Outer Planets
The Outer Planets
Second largest planet in solar system.
Thick atmosphere of hydrogen and helium with clouds and storms.
Planet with the smallest density – it is less dense than water.
Saturn

The Outer Planets
Saturn’s rings:rings are wide and thinmade of chunks of ice and rock that
are as small as a grain of sand to as large as a house
divided into regions that have dozens of smaller rings so thousands of rings in all
each ring orbits at a different speed

Uranus
The Outer Planets
The Outer Planets
Atmosphere of mainly hydrogen and helium.
Looks bluish because of methane in its atmosphere.
Only planet with equator at almost a right angle to its orbit (looks like it is lying on its side).

Uranus’s Moons:named for characters in Shakespeareappear to be ½ ice and ½ rockMiranda – smallest and closest moon
that has fault line that is 12 x deeper than the Grand Canyon
some moons are very close together

Neptune
The Outer Planets
The Outer Planets
Distance from sun makes it dark and cold.
Made of mostly hydrogen and helium.
Has not yet had a full rotation around the sun since its discovery in 1846.
Neptune

The Outer Planets
Neptune’s Moons:Triton –
○ has ice volcanoes that spit out a mixture of liquid nitrogen, methane, and dust that instantly freezes and snows back onto the surface
○ one of the coldest objects in the solar system at -400ºF
○ only moon in solar system that orbits opposite to the planet’s rotation
