1. The Outer Planets

2. Question:
What characteristics are common to all the outer planets?

3. Jupiter
Mass: 1.90 x 1027 kg (1,900,000,000,000,000,000,000,000,000 kg)
Diameter: 142,800 km
Avg. distance from sun: AU or 778,412,020 km

4. Jupiter Rotation (day): 9.8 Earth hours
Revolution (year): Earth years
Structure: no solid crust, gas swirling around a liquid layer, solid core

5. Jupiter Atmosphere: 80% hydrogen 19.3% helium 0.7% methane (CH4)
Colorful bands
Red spot is a giant storm that has been going for hundreds of years

6. Jupiter 300 times bigger than Earth At least 63 moons
One, Europa, is covered by water ice
May support life

7. Video: Jupiter write and be prepared to discuss three things you did not know before watching the video

8. Saturn Mass: 5.69 x 1026 kg Diameter: 120,660 km
Avg. distance from sun: AU

9. Saturn Rotation: 10.2 Earth hours Revolution: 29.46 Earth years
Atmosphere:
90% hydrogen
9.95% helium
.05% methane

10. Saturn Saturn is less dense than water and would float
At least 60 moons
Outer gas layer, a
thick liquid layer
surrounding a solid
core.

11. Saturn Rings are most prominent feature 270,000 km in diameter
Only a few hundred meters thick
Particles range from dust-sized to chunks as large as a house.

13. Uranus Mass: 8.68 x 1025 kg Diameter: 51,118 km
Avg. distance from sun: AU or 2,870,972,200 km

14. Uranus Rotation: 17.9 Earth hours
it spins on its side; moves around the sun like a rolling ball.
Possibly because it was hit by a large object
Revolution: 84 Earth years

15. Uranus Atmosphere: 83% hydrogen 15% helium 2% methane Makes planet
appear blue
Beneath atmosphere is a thick, slushy layer of water and ammonia

16. Uranus Rings are narrow with a vertical alignment at least 27 moons
- One named Titania has an icy cracked surface once thought to be an ocean.

17. Neptune Mass: 1.02 x 1026 kg Diameter: 49,528 km
Avg. distance from sun: AU or 4,498,252,900 km

18. Neptune
Rotation: 19.1 Earth hours
Revolution: Earth years

19. Neptune Atmosphere: 74% hydrogen 25% helium 1% methane
Has visible clouds that come and go

20. Neptune Faint, dark ring system At least 13 moons
Largest moon, Triton, has geysers that erupt nitrogen.

21. Neptune Discovered first by mathematics.
Uranus’ orbit was not mathematically possible unless there was another planet pulling on it.
Winds sometimes exceed 1,000 km/hour.

23. Question:
What are the similarities and differences between the inner and outer planets?
