The Inuit group is a dynamical grouping of the prograde irregular satellites Saturn which follow similar orbits. Their semi-major axes range between 11 and 18 Gm, their inclinations between 40° and 50°, and their eccentricities between 0.15 and 0.48.

The group is very homogenous, all satellites displaying light-red colour (colour indices B−V = 0.79 and V−R = 0.51, slightly redder than Gallic group). The spectral homogeneity are consistent with a common origin in the break-up of a single object but the dispersion of the orbital parameters requires further explanation [1]. Recently reported secular resonances among the members could provide the explanation of the post-collisional dispertion.

The diagram illustrates the Inuit group in relation to other irregular satellites of Saturn. The eccentricity of the orbits is represented by the yellow segments (extending from the pericentre to the apocentre) with the inclination represented on Y axis.

The five members of the group are (in order of increasing distance from Saturn):

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