Pallene (provisional designation S/2004 S 2) is a natural satellite of Saturn. It was discovered by the Cassini Imaging team led by Carolyn C. Porco, et al. in 2004. Pallene orbits Saturn at a distance of about 211 Mm (thus its period is 1.142 d) and is about 4 kilometres in diameter.
The names Methone and Pallene have been provisionally approved by the IAU Division III Working Group for Planetary System Nomenclature. They should be officially approved at the IAU General Assembly in 2006. Pallene was one of the Alkyonides, the seven beautiful daughters of the Giant Alkyoneus.
Discovery image of S/2004 S 2 Supposing its density equal to Mimas' (1.17 t/m³), one can estimate the following:
- mass 3.92×1013 kg
- gravity 0.000 65 m/s²
- escape velocity 0.0016 m/s
