1. Moons of Gas Giants

3. Jupiter

4. Io Innermost moon Composed of Sulfur Volcanically Active
Heat is generated by tidal forces

5. Europa Smallest of the Galilean moons Few craters Faults
Smoother than a ping-pong ball
Underwater ocean
Life?

6. Ganymede Largest moon in the solar system Two types of terrain
Dark terrain is older
Light terrain is covered in ridges
Has a magnetic field

7. Callisto 3rd largest moon in solar system High crater density
Is not effected by tidal heating
Low density
Most likely place to be used as a base

8. Saturn

9. Mimas:
composed mostly of water
not perfectly spherical
Herschel

10. Enceladus: 6th largest moon ice on surface ~ 100% reflectivity
active eruptions

11. Tethys:
has one of most visual reflective surface
Ithaca Chasma

12. Dione:
3rd densest
heavily cratered terrain
‘wispy terrain’

13. Titan Largest moon of Saturn and 2nd largest moon in the solar system.
Discovered by Christiaan Huygens
Has an atmosphere denser than that of Earth
Life? May this help us discover the learn more about earth’s beginnings?

14. Saturn: Hyperion Irregular (nonspherical) body
Discovered by George Phillips Bond, American
composed primarily of water ice with only a small amount of rocky material

15. Saturn: Iapetus 3rd largest moon of Saturn
Discovered by Cassini in 1671
With a density of only 1.1,
Very Unique moon, jet black on one side, and snowy white on the other.

16. Uranus

17. Miranda Most Geologically active moon of Uranus
Possible heat source from collision

18. Ariel Youngest and brightest moons of Uranus 70% is composed of ice
Has some minor geologic activity

19. Umbriel Darkest of Uranus’s moons
Most prominent feature is a large impact crater
Black material thought to be dug up from past impact

20. Titania Uranus’s largest moon Is thought to be 50% ice
Has many deep faults

21. Oberon Second largest moon of Uranus Has many faults
Core makes of 63% of Oberon
Has a large crater count

22. Neptune

23. Triton Retrograde orbit Has a high inclination orbit
Is the same size as Earth’s moon
Thought to be a captured moon, either had a collision or had a twin

24. Triton Very high Albedo Few craters Geologically active
Cantaloupe terrain
