SOLAR SYSTEM

MOONS OF SATURN

Planet Saturn has 145 moons. Titan, the largest moon, contains a thick atmosphere and represents 96% of the mass of all Saturnian moons. Titan can be viewed with binoculars. In addition, there are thousands of small "propeller" moonlets believed to be embedded in the A ring of Saturn.

Ocean moons

Titan, Enceladus, Dione, and Mimas are believed to harbor subsurface oceans.

Shepherd moons

Saturn's ring shepherd moons are Atlas (A Ring), Pan (Encke Gap), Daphnis (Keeler Gap), Pandora (F Ring), and Prometheus (F Ring).

Ring-maker moons

The following moons are the source material for a number of outer rings and ring arcs beyond the main F Ring.

Orbital groups

Saturn moons can be classified into various groups whereby all moons in a group have similar orbits and often share a common origin.

  • Inner large group - 4 large moons that orbit inside of the E Ring

  • Alkyonides - 3 small moons that orbit between Mimas and Enceladus inside of the E Ring

  • Outer large group - 4 large moons that orbit outside of the E Ring

  • Gallic group - 4 small irregular outer moons

  • Inuit group - 8 small irregular outer moons

  • Norse group - 46 small irregular outer moons

Provisional moons are named according to the year and order in which they were discovered. Once more data from these moons are confirmed, they will be assigned permanent "friendly" names.
