Prometheus, Moon of Saturn

Prometheus is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 875,749.31 km. The furthest it gets from its orbital parent (apoasis) is 139,687 km. Its mass is estimated/calculated at being 160,956,989,714,639,000 kg. Its density has been calculated at being 0.48 g/cm3. Its volume is 335,367 km3.

It was discovered in the year 1980 by S. A. Collins, D. Carlson, Voyager 1.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 0.613 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 139,380 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Prometheus is 270.8 km. The mean radius, that is the average radius of Prometheus is 43.1 km. The surface area of Prometheus is 23,343.42 km2. The surface gravity of the said item is 0.006 m/s2. The average orbit velocity, that is the speed at which it orbits is 59,526.2 km/h.

The orbital inclination, the angle at which Prometheus orbits in relation to the orbital plane is 0.008 degrees. The orbital eccentricity is 0.0022, it is the degree at which Prometheus orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
