Fenrir is a Moon that orbits round Saturn rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 140,459,769.23 km. The furthest it gets from its orbital parent (apoasis) is 25,445,779 km. Its density has been calculated at being 2.3 g/cm3. Its volume is 2.3 g/cm3. It was discovered on 12 December 2004 by Scott S. Sheppard, David L. Jewitt and Jan T. Kleyna.
The Semi-Major Axis of the orbit is 22,454,800 km, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Fenrir is 12.6 km. The mean radius of Fenrir is 2.0 (assuming an albedo of 0.04) km. The surface area of Fenrir is 50.27 km2. The average orbit velocity, that is the speed at which it orbits is 4,643.3 km/h.
The orbital inclination, the angle at which Fenrir orbits in relation to the orbital plane is 164.444 degrees. The orbital eccentricity is 0.1332, it is the degree at which Fenrir orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
