S/2006 S 19

← back to Outer Saturnian Moons

S/2006 S 19 is ∼3½ kilometers in size and thus one of the small Irregular moons of Saturn. Its discovery has been announced in May 2023 joint with sixty-one other outer Saturnian moons. Its mean distance to Saturn is ∼23¼ million kilometers, with one revolution around the planet on a retrograde orbit requiring 3 years and 7½ months.

With a very high eccentricity of ∼0.58, the orbit of S/2006 S 19 is very elongated and leads it among furthest from Saturn (∼37 million kilometers) of all moons as well as among closest (∼10 million kilometers) of Saturn’s retrograde objects.

This object has not been named yet. We made no attempt to observe it with Cassini because it was unknown at the time Cassini was active. Note that the orbital elements in the MPEC announcement are current values, not mean elements (time-averaged over a few thousand years) as given for the pre-2023 announced objects.
