Greip, Moon of Saturn

Greip is a Moon that orbits round the planet Saturn. It is also know by other designations, SLI, S/2006 S4. Its density has been calculated at being 2.3. Its volume is 113.

Greip was discovered on 6 March 2006 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 921 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 3km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Semi-Major Axis of the orbit is 18210, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Greip is 18.8 km. The surface area of Greip is 113.10. The Mean orbit velocity, that is the speed at which it orbits is 5029.00 km/h. The is the average distance in km of the object is from its parent 18442200.00.

The orbital inclination, the angle at which Greip orbits in relation to the orbital plane is 179.8 degrees. The orbital eccentricity is 0.3160, it is the degree at which Greip orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
