Helene, Moon of Saturn

Helene is a Moon that orbits round the planet Saturn. It is also know by other designations, SXII, S/1980 S6. Its mass is estimated/calculated at being 11,389,880,091,538,700 kg. Its density has been calculated at being 0.5. Its volume is 22836.

Helene was discovered on 1 March 1980 by P. Laques, J. Lecacheus.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 2.7369 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 18km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 33 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 377.4, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Helene is 110.6 km. The surface area of Helene is 3,892.56. The surface gravity of the said item is 0.002. The Mean orbit velocity, that is the speed at which it orbits is 36100.50 km/h. The is the average distance in km of the object is from its parent 377420.00.

The orbital inclination, the angle at which Helene orbits in relation to the orbital plane is 0 degrees. The orbital eccentricity is 0.0071, it is the degree at which Helene orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
