Saturn's Moons

The most current number of moons, as of March 1, 2008 is 60. To see there locations and date of discovery, go to Sam Sheppard's site which is devoted to a study of the moons of the solar system.

The diagram above depicts the location of Saturn's main moons as well as the location of the ring system. This page is dedicated to some of the major moons of Saturn's system. After going through this page, you will be asked to move to a webpage that explores Saturn's rings in greater detail. One big request of you is that you go into the webpage exclusively built for a discussion of Titan. Titan may be the most exciting object of study in our solar system since it holds an atmosphere with many constituents similar to Earth, and with the possibility of hydrocarbons and biomolecules on its cold surface.

Mimas ("MY mas") is the seventh of Saturn's known satellites:
orbit: 185,520 km from Saturn
diameter: 392 km
mass: 3.80x1019 kg

 

 

 

 

 


 

 

 

Enceladus ("en SEL a dus") is the eighth of Saturn's known satellites:
orbit: 238,020 km from Saturn
diameter: 498 km
mass: 7.30x1019 kg

 

 

 

 

 

 

Tethys ( "TEE this" ) is the ninth of Saturn's known satellites:
orbit: 294,660 km from Saturn
diameter: 1060 km
mass: 6.22x1020 kg

 

 

 

 

 

Dione ( "dy OH nee" ) is the twelfth of Saturn's known satellites:
orbit: 377,400 km from Saturn
diameter: 1120 km
mass: 1.05x1021 kg

 

 

 


Rhea ("REE a") is the fourteenth of Saturn's known satellites and the second largest:
orbit: 527,040 km from Saturn
diameter: 1530 km
mass: 2.49x1021 kg

 

 

 

 

 

Titan is the fifteenth of Saturn's known satellites and the largest:
orbit: 1,221,830 km from Saturn
diameter: 5150 km
mass: 1.35x1023 kg

 

 

 

 

 

 

One of the principal objectives of the Voyager 1 mission was the study of Titan. Voyager 1 came within 4000 km of the surface. We learned more in the few minutes of that encounter than in the previous 300 years.

THIS MAY BE THE MOST EXCITING MOON IN THE SOLAR SYSTEM, AND THEREFORE TITAN HAS ITS OWN WEBPAGE FOR MY CLASS.

 

Iapetus ("eye AP i tus" ) is the seventeenth of Saturn's known satellites and the third largest:
orbit: 3,561,300 km from Saturn
diameter: 1460 km
mass: 1.88x1021 kg

 

 

 

 

Other smaller moons of interest that have been recently photographed by the Cassini spacecraft:

Hyperion

 

 

 

 

 

 

Phoebe

 

 

 

 

 

 

 

There are other moons of Saturn as well, but these are the moons that I chose to include in this course. If you are interested in learning more about Saturn's moons, you can connect to the Nine Planets website, from which much of this information has been directly copied, or else go to the LANL or JPL sites.

Now, please move ahead to Saturn's Rings, return to Saturn, or the Planet Introduction, or even the Syllabus.
