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.

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.
