Discovery of S/2004 S 6

28 October 2004

S/2004 S 6 is a provisional designation given to an object detected in images from the Cassini spacecraft, which entered orbit around Saturn in 2004. Provisional names of this form are assigned to possible new moons: the S stands for Saturn, followed by the year and a running number. Objects of this kind, found close to Saturn's rings, often turn out to be clumps of material or transient features rather than true moons, and some were never confirmed as lasting bodies. The designation records the early phase of Cassini's long study of the Saturn system, which found many new small moons and revealed the complex behaviour of the rings.
