Moons, Rings, and Pluto Terms (Chapter 8)1.Cassini Division- A relatively empty gap in Saturn’s ring system, discovered in1675 by Giovanni Cassini. It is now known to contain a number of thin ringlets.2.B Rings- One of three Saturnian rings visible from earth. The B ring is thebrightest of the three, and lies just past the Cassini Division, closer to the planetthan the A ring.3.C Rings- One of three Saturnian rings visible from Earth. The C ring lies closestto the planet and is relatively thin compared to the A and B rings.4.Encke Gap- A small gap in Saturn’s A ring5.Roche Limit- Often called the tidal stability limit; the Roche limit gives thedistance from a planet at which the tidal force (due to the planet) betweenadjacent objects exceeds their mutual attraction. Objects within this limit areunlikely to accumulate into larger objects. The rings of Saturn occupy the regionwithin Saturn's Roche limit.
