Aegir, Moon of Saturn

Aegir is a Moon that orbits round the planet Saturn. It is also know by other designations, SXXXVI, S/2004 S10. Its density has been calculated at being 2.3. Its volume is 113.

Aegir was discovered on 12 December 2004 by Scott S. Sheppard, David L. Jewitt and Jan T. Kleyna.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 1117 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 3km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Semi-Major Axis of the orbit is 20740, 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 surface area of Aegir is 113.10. The Mean orbit velocity, that is the speed at which it orbits is 4781.30 km/h. The is the average distance in km of the object is from its parent 20749800.00.

The orbital inclination, the angle at which Aegir orbits in relation to the orbital plane is 166.7 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.

Aegir Mythology Legend

Unlike other planetary moons, this moon is named after a Norse god, Aegir. Aegir was a Norse entity, an ambiguous creature that wasn't a god or other familiar creature like a dwarf. Aegir was associated with the ocean. Although not a god, he was known to friend and socialise with them, having parties.

Aegir's wife was known as Ran and together they had nine daughters. Each of the daughters was associated with being spirits of the waves. The daughters were named Blóðughadda (Bloody Hair), Bylgja (billow), Dröfn or Bára (foaming sea), Dufa (Wave), Hefring or Hevring (Lifting), Himinglæva (Transparent on Top), Hrönn (Wave), Kólga (Cool Wave) and Uðr or Unn (Wave).
