# Hyrrokkin, Moon of Saturn

**Hyrrokkin** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 112,647,481.66 km. The furthest it gets from its orbital parent (apoasis) is 24,499,484 km. Its density has been calculated at being 2.3 g/cm3. Its volume is 113 km3.

Hyrrokkin was discovered on 12 December 2004 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 931.87 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Semi-Major Axis of the orbit is 18,437,300 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Hyrrokkin is 18.8 km. The mean radius of Hyrrokkin is 3.0 (assuming an albedo of 0.04) km. The surface area of Hyrrokkin is 113.10 km2. The average orbit velocity, that is the speed at which it orbits is 5,037.2 km/h.

The orbital inclination, the angle at which Hyrrokkin orbits in relation to the orbital plane is 151.245 degrees. The orbital eccentricity is 0.3288, it is the degree at which Hyrrokkin orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
