Planetary Moons NAQT
Planetary moons from NAQT website. Answer has both moon and planet name.
| Question | Answer |
|---|---|
| Named for the mythical boatman of the Greek underworld, the largest moon relative to the size of its orbiting planet is thought to have liquid water on its surface. | Charon (Pluto) |
| Named for two sons of Ares and Aphrodite, these satellites were discovered two days apart and are both heavily crated, rich in carbon, and thought to have water ice. | Deimos and Phobos (Mars) |
| This one of the Galilean moons, discovered in 1610. There is the possibility of an active sea of liquid water beneath the surface. The most striking feature of the surface is a series of dark streaks that may be due to geysers or volcanic eruptions. | Europa (Jupiter) |
| The largest satellite in the solar system, this Galilean moon is larger than Mercury, but has only half its mass. | Ganymede (Jupiter) |
| Named for a lover of Zeus, this satellite is dotted with active volcanoes, calderas, and other signs of geological activity. The eruptions are believed to consist of sulfurous compounds that comprise the thin atmosphere of this planet. | Io (Jupiter) |
| Discovered by Gerard Kuiper and named for the daughters of Nereus and Doris, this satellite has the most eccentric orbit of any known satellite, ranging from 1.3 million kilometers to 9.6 million. | Nereid (Neptune) |
| Named for the King of the Fairies in A Midsummer Night's Dream, this satellite is the second largest of its planet and about half ice, half rock, like most of its plantet's satellites. | Oberon (Uranus) |
| It is the only satellite to have a substantial atmosphere. Its significant atmosphere, a mix of nitrogen (80%), methane (20%), and argon (trace), also makes it unique among satellites | Titan (Saturn) |
| Named for Oberon's wife, this satellite's surface is an odd mix of craters and valleys. One theory regarding this is that it began as a liquid, then cooled surface first. | Titania (Uranus) |
| It features seismic activity in the form of ice volcanoes, a tenuous nitrogen-methane atmosphere, and a southern hemisphere "ice cap" of nitrogen and methane, possibly due to its odd rotational axis. | Triton (Neptune) |
