Erriapus, Moon of Saturn

Erriapus is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 104,333,269.82 km. The furthest it gets from its orbital parent (apoasis) is 25,846,491 km. Its mass is estimated/calculated at being 764,320,900,879,568 kg. Its density has been calculated at being 2.3 g/cm3. Its volume is 524 km3.

It was discovered in the year 2000 by B. Gladman, J. Kavelaars, J.-M. Petit, H. Scholl, M. Holman, B.G. Marsden, P. Nicholson and J.A. Bur.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 871.14 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 17,611,400 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Erriapus is 31.4 km. The mean radius, that is the average radius of Erriapus is 5 km. The surface area of Erriapus is 314.16 km2. The surface gravity of the said item is 0.002 m/s2. The average orbit velocity, that is the speed at which it orbits is 4,992.2 km/h.

The orbital inclination, the angle at which Erriapus orbits in relation to the orbital plane is 38.649 degrees. The orbital eccentricity is 0.4676, it is the degree at which Erriapus orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
