**Bestla** is a Moon that orbits round the planet Saturn. It is also know by other designations, SXXXIX, S/2004 S18. Its density has been calculated at being 2.3. Its volume is 180.

Bestla was discovered on 12 December 2004 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 1084 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 4km. 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 20130, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Bestla is 22.0 km. The surface area of Bestla is 153.94. The Mean orbit velocity, that is the speed at which it orbits is 4595.20 km/h. The is the average distance in km of the object is from its parent 20278000.00.

The orbital inclination, the angle at which Bestla orbits in relation to the orbital plane is 145.2 degrees. The orbital eccentricity is 0.4738, it is the degree at which Bestla orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
