Norse group

Unlike the Inuit and Gallic groups, the orbital parameters are widely dispersed and the group is likely to be composed from a number of subgroups with more homogeneous orbital and physical parameters.

The International Astronomical Union (IAU) reserves names taken from Norse mythology (mostly giants) for these moons.

The exception is Phoebe (Greek mythology), the largest, which was discovered long before the others.

A team led by Scott S. Sheppard using the Subaru Telescope at Mauna Kea discovered 20 new moons, each about 5 kilometres (3.1 miles) in diameter.

Diagram illustrating the orbits of the irregular satellites of Saturn, with major groups and moons labeled. The inclination and semi-major axis are represented on the Y and X-axis, respectively. The satellites with inclinations below 90° are prograde , those above 90° are retrograde . The X-axis is labeled in terms of Saturn's Hill radius .
