The Gallic group is a dynamical grouping of the prograde irregular satellites of Saturn following similar orbits. Their semi-major axes range between 16 and 19 Gm, their inclinations between 35° and 40°, and their eccentricities around 0.53. The International Astronomical Union (IAU) reserves names taken from Gallic mythology for these moons. Similar mean orbital elements led the discoverers to postulate a common origin for the group in a break up of a larger body.
