1. The Outer Planets!

2. Jupiter! hydrogen and helium atmosphere,
no solid surface, all gas! possibly a solid core?
hydrogen and helium atmosphere,
the swirls are clouds, the colors are
from temperature differences
-temp= C
- 1 day = 10 hours
- 1 year = 12 earth years
- 142,800 km. diameter

3. at least 28 moons:
- Io= active volcanoes
- Callisto= icy, craters
- Ganymede = largest
- Europa may have liquid water
underneath frozen surface
interesting fact: Jupiter’s red “eye” is actually
a hurricane-like storm bigger than the Earth!

4. Saturn! -surface like jupiter, but less spectacular storms.
-Rings of icy rocks
temperature= COLD!
-1 day = 10 hours
- 1 year = 30 earth years
- 120, 540 km. diameter

5. at least 30 moons:
Titan is larger than our moon,
has thick atmosphere.
interesting fact:
Saturn’s rings sometimes cross.
There are two small moons between ring bands:
promethus and pandora
(one on either side of most outer band)

6. Uranus! hydrogen and methane gas - temp = -330 F - 1 day = 17 hours
-1 year = 84 Earth years
- 51,200 km. diameter

7. at least 21moons: Puck,
Portia, Bianca, Cressida,
Juliet, Desdemona,
Miranda… all names
from Shakespearean
plays!
interesting fact: uranus is
tipped almost completely
on its side! And it has
thin rings!

8. Neptune! -hydrogen, helium, methane temp= COLD! - 1day = 20 hours
- 1 year = 165 earth years
- 49,500 km. diameter

9. at least 8 moons: Triton is largest
Interesting fact: the tidal pull will tear Triton
apart to form ring fragments!

10. Pluto (though not a planet!) solid frozen surface temp = varying,
but VERY COLD
- 1 day = 6 days
- 1 year = 249 earth years
- 2, 200 km. diameter

11. 3 moons: Charon, and 2 newly found, not
yet named. Very close to pluto.
Interesting fact: Pluto and Charon are
so pulled by gravity that they always
face each other!
