Aegir, Moon of Saturn

Aegir 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 128,272,946.86 km. The furthest it gets from its orbital parent (apoasis) is 25,987,050 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 20,749,800 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Aegir is 18.8 km. The mean radius of Aegir is 3.0 (assuming an albedo of 0.04) km. The surface area of Aegir is 113.10 km2. The average orbit velocity, that is the speed at which it orbits is 4,781.3 km/h.

The orbital inclination, the angle at which Aegir orbits in relation to the orbital plane is 167.106 degrees. The orbital eccentricity is 0.2524, it is the degree at which Aegir orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
