| Question | Answer |
| The Moon | Leading theory on how this moon was formed is called Giant Splat Theory—early Earth was hit (splat) and the debris that got chucked off went into orbit and eventually coalesced into the moon. |
| The Moon | The maria or seas of the moon are crater impact sites that have been filled in with runny lava that seeped up through weak spots and cracks of the moon’s surface. |
| The Moon | LCROSS Impact Data indicates there is plenty of ice on this Moon in deep craters where sunlight doesn’t reach. |
| Io | inner most moon of Jupiter and 4th largest moon in solar system |
| Io | Still hot inside due to tidal heating from Jupiter |
| Io | Over 400 active volcanoes (sulfur & sulfur dioxide) |
| Io | Some peaks on this moon are taller than Everest! |
| Io | Made of silicate rock (no ice on this one) |
| Europa | Made of silicate rock, iron core, subsurface OCEAN of water, ice layer on top-kept warm by tidal heating from Jupiter (maybe life in it?) |
| Europa | Striated surface, craters are rare |
| Europa | Water vapor plumes detected erupting |
| Enceladus | Cassini mission just discovered a liquid water ocean under its icy surface. |
| Titan | Largest moon of Saturn. Larger by volume than Mercury and 2nd largest moon in Solar System |
| Titan | Very substantial atmosphere which is Nitrogen Made of water ice and rocky material |
| Titan | Stable liquid lakes on surface of hydrocarbons-liquid ethane & methane (size of Great Lakes) Possible cryovolcanoes |
| Titan | Few impact craters Presence of organic molecules!! Which are a precursor to life! |
| Miranda | Has large racetrack like features called ovoids. Mostly rock and ice More geological activity than any other Uranian moon |
| Triton | Largest moon of Neptune, little smaller than the moon |
| Triton | Most likely Neptune gravitationally captured it. Was once a Kuiper Belt Object (KBO) |
| Triton | The only large moon in solar system that rotates around its planet in the opposite direction of the planet’s rotation (retrograde) |
| Triton | Ice volcanoes Ice flows Cantaloupe terrain Nitrogen dominated atmosphere Surface may be nitrogen ice |
| Charon | Discovered in 1978. Half the size of Pluto. |
| Nix and Hydra | Discovered in 2005 by Hubble Space Telescope. |
| Kerebos and Styx | Discovered by Hubble Space Telescope in 2011. |
