# Prometheus, Moon of Saturn

Prometheus is a Moon that orbits round the planet Saturn. It is also know by other designations, SXVI, S/1980 S27. Its mass is estimated/calculated at being 160,956,989,714,639,000 kg. Its density has been calculated at being 0.48. Its volume is 335367.

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 Equatorial Radius of the object is 43km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 80 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 139.353, 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 surface area of Prometheus is 23,343.42. The surface gravity of the said item is 0.006. The Mean orbit velocity, that is the speed at which it orbits is 59526.20 km/h. The is the average distance in km of the object is from its parent 139380.00.

The orbital inclination, the angle at which Prometheus orbits in relation to the orbital plane is 0 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.
