Describe Saturn's rings. |
While Saturn was discovered by Galileo, its rings were discovered by Huygens (as was Saturn's satellite, Titan). The rings can be divided into groups based on their distance from the planet. There are seven groups (A,B,C,D,E,F,G). There is a division between groups A and B called the Cassini Division and is caused by gravitational interruptions from Saturn's satellite, Mimas. The rings ride exactly above Saturn's equator and are very bright. Saturn's B ring has dark radial features called spokes. The rings are composed of water ice. |

Describe Saturn's satellites. |
1. Titan contains a thick atmosphere composed of mainly nitrogen (like Earth). Contains cryovolcanoes that spew cold water and ice. 2. Mimas 3. Lapetus 4. Enceladus -Saturn also has what are called Shepherd satellites that are located in between the rings and act to stabilize them. i.e. Prometheus and Pandora which are shepherd satellites that stabilize the F ring. |
