LIST OF MOONS included in the MOON exhibition
Earth's Moon
Luna
cratered highlands, dark basalt maria (found mostly on the Earthward side)
Moon of Mars
Deimos
irregular shape, heavily cratered
Moons of Jupiter
Io
the most geologically active object in the solar system, active volcanoes,
thin sulphur dioxide atmosphere, very weak magnetosphere, visible aurorae
Europa
harbours a vast ocean of salty water under a crackled crust of water ice,
no impact craters, substantial magnetic field, tenuous oxygen atmosphere
Ganymede
dark, old cratered terrain and lighter, grooved terrain, crust is slushy water
ice, tectonic activity, cryovolcanism, magnetic field, polar aurorae, tenuous
oxygen atmosphere, largest moon in the solar system, larger than planets Mercury
and Pluto
Callisto
monotonous cratered terrain, large multiple basin-ringed structure "Valhalla",
crust is soft ice over an ocean of slushy water ice, tenuous carbon-dioxide
atmosphere, weak magnetic field
Moons of Saturn
Mimas
orbits close to Saturn's rings and is therefore heavily cratered, largest
feature is the enormous "Herschel" crater
Enceladus
very bright, covered with fine crystals of pure water ice, much of moon is
devoid of impact craters, cryovolcanism
Tethys
reflective surface, heavily cratered, large surface cracks
Dione
reflective surface, heavily cratered, bright streaks on trailing face, ice
maria
Rhea
very reflective surface, heavily cratered, bright whispy terrain on trailing
face
Iapetus
strong contrast between dark leading face and pale trailing face
Titan
larger than planet Mercury, about half the size of Earth, dense nitrogen atmosphere,
seas of hydrocarbon
Moons of Uranus
Miranda
displays a large variety of surface terrains: ridges, valleys, faults, craters
Umbriel
the darkest of Saturn's moons, bright spot on sun-ward side
Titania
old surface, heavily cratered, some surface cracks
Moons of Neptune
Proteus
dark as soot, one of the darkest objects in the solar system, heavily cratered,
irregular shape, as large as a moon can be without being pulled into a spherical
shape by its own gravity
Nereid
heavily cratered, irregular shape
Triton
frozen surface of water ice, cantaloupe-like terrain, frozen lakes of water
ice, no impact craters, pink nitrogen frost on polar cap due to nitrogen geysers,
thin nitrogen atmosphere
