List of Saturn's moons

from Wikipedia, the free encyclopedia

The following table contains the most important data of the 82 natural satellites of Saturn known so far .

New discoveries carry a provisional numerical code until their orbits are known with sufficient accuracy for predicting orbital positions; Then they receive a consecutive Roman number from the International Astronomical Union and, according to tradition, after agreement, they also get a name from classical mythology confirmed. Until the end of the 19th century, the numbers were assigned according to the increasing size of the orbits.

Due to the improved observation possibilities, both from space probes and from Earth, the total number of observed moons increased annually from 2003 to 2009, although the newly discovered moons only have radii of a few kilometers.

Not included in the list is the supposed Saturn moon Themis , the discovery of which William H. Pickering announced in 1905, but which was never seen again and is considered non-existent. Also not included are the three still questionable satellites S / 2004 S 3, S / 2004 S 4 and S / 2004 S 6, which may have been observed between Prometheus and Pandora close to Saturn's F-ring.

An orbit inclination of more than 90 ° means that the satellite is orbiting Saturn retrograde. As a rule, moons move around the planet in the same direction of rotation as the planet rotates around its own axis.

TheIrregulars SATURN.svg

The diagram shows the orbital half-axes of the outer moons of Saturn (abscesses, in million km) against their orbital inclination (ordinate, in degrees): The circle sizes do not show the relative lunar radii to the orbital elements. The horizontal lines represent the area between perihelion and aphelion of the respective lunar orbit.
