Phoebe, Moon of Saturn

Phoebe is a Moon that orbits round the planet Saturn. Its mass is estimated/calculated at being 8,290,633,771,893,670,000 kg. Its density has been calculated at being 1.638. Its volume is 5059848.

Phoebe was discovered on August 1898 by W. Pickering.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 548 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 107km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 367 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 12944, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Phoebe is 669.2 km. The surface area of Phoebe is 142,530.92. The surface gravity of the said item is 0.049. The Mean orbit velocity, that is the speed at which it orbits is 6118.50 km/h. The is the average distance in km of the object is from its parent 12947913.00.

The orbital inclination, the angle at which Phoebe orbits in relation to the orbital plane is 174.8 degrees. The orbital eccentricity is 0.1634, it is the degree at which Phoebe orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
