Moons of Gas Giants

Jupiter

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

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

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

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

Saturn

Mimas: composed mostly of water not perfectly spherical Herschel

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

Tethys: has one of most visual reflective surface Ithaca Chasma

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

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?

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

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.

Uranus

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

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

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

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

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

Neptune

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

Triton Very high Albedo Few craters Geologically active Cantaloupe terrain
