Outer Solar System

2. Information The atmosphere of a gas giant is deep, with many clouds
Gas giant rings are made from chunks of ice
All orbits of planets, asteroids, and comets are ellipses.
Gas makes up most of their atmosphere
Atmosphere is denser and hotter as you go deeper

3. Jupiter Largest planet in solar system
Clouds look white because they’re made of ice crystals…frozen ammonia not frozen water
Lower clouds are brown or red and made of different chemicals
Great Red Spot- large storm which is twice as wide as Earth and over 100 yrs old (no land to slow down storms)

4. Saturn Saturn’s rings are zones of ice that orbit the planet
Many storms; striped clouds deeper in atmosphere
Most well known for rings (wide, flat zone of small particles that orbit planet)
Rings have bright and dark stripes that change over time
Orbits Sun once every 30 years

5. Uranus Twice Saturn’s distance from the Sun
Moves slowly along it’s orbit---84 years to travel once around Sun
Rings and moons around
Uranus – a lot of methane
too   
Seems to spin on its side
(possible large collision?)

6. Neptune
Same outside temperature as Uranus because it’s hotter inside the planet
Clouds of methane ice crystals
Dark colors=storm systems
(Just imagine a huge methane storm
that never ends )

7. What is in the rings that surround many of the planets
What is in the rings that surround many of the planets? Frozen ice, dust, small rocks, and gas.
This planet’s axis is tilted so severely it looks like it must have once been hit by another planet sized object? Uranus

13. Review What planet has the Great Red Spot?
Jupiter
Rings of gas giants are made from ______
Chunks of ice, dust, and gas
The atmosphere is more _______ and more ________ the farther you travel into a Gas Giant’s atmosphere.
Dense
Hot
What does AU mean?
Average distance from the Sun (93,000,000 miles)

14. Drawf Planets
Dwarf planets:
Pluto (small, icy, low density, one moon, its orbit crosses that of Neptune)
Pluto was demoted from a planet to a dwarf planet in August 2006.
Ceres (the largest known asteroid orbiting between Mars and Jupiter) is also considered a dwarf planet.
Xena (2003 UB313) - a body larger and farther away than Pluto
There are a number of other potential candidates for dwarf planets.
