Astronomy: Saturn

4. The most prominent feature of Saturn composed of billions of small particles of ice and rock orbiting the planet.
6. An inner shepherd moon of Saturn that helps shape the F Ring.
8. A moon of Saturn known for its enormous impact crater Herschel which gives it a resemblance to the Death Star.
10. Saturn's largest moon and the only moon in the Solar System with a thick atmosphere and liquid on its surface.
11. Small moons that orbit near the edges of rings using their gravity to keep the ring particles in a narrow band. (e.g. Prometheus and Pandora)
12. Saturn's second-largest moon a heavily cratered icy body.
15. A small icy moon of Saturn that is known for its geysers of water vapor erupting from its south pole suggesting a subsurface ocean.
16. The classification for a large planet composed mainly of hydrogen and helium just like Jupiter and Saturn.
17. The joint NASA/ESA/ASI space probe that studied Saturn and its system from 2004 to 2017. The Huygens probe landed on Titan.

1. An outer shepherd moon of Saturn that works with Prometheus to confine the F Ring.
2. A phenomenon where water particles from the rings are pulled into Saturn's atmosphere by its magnetic field.
3. The largest gap in Saturn's rings located between the A Ring and B Ring.
5. The flattened appearance of Saturn caused by its fast rotation and low density making it bulge at the equator.
7. The thousands of narrow individual rings that make up the broader ring system of Saturn.
9. A moon of Saturn famous for its dramatic two-tone coloration with one hemisphere being bright and the other very dark.
11. The sixth planet from the Sun and the second-largest in the Solar System famous for its extensive ring system.
13. The primary material that makes up the vast majority of Saturn's rings.
14. A persistent six-sided jet stream pattern located at Saturn's north pole.
