# Phoebe, Moon of Saturn

**Phoebe** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 80,808,357.62 km. The furthest it gets from its orbital parent (apoasis) is 15,063,602 km. Its mass is estimated/calculated at being 8,290,633,771,893,670,000 kg. Its density has been calculated at being 1.638 g/cm3. Its volume is 5,059,848 km3.

Phoebe was discovered on August 1898 by W. Pickering. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 548.02 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Semi-Major Axis of the orbit is 12,947,913 km, which is the furthest point from the centre to the edge of an elliptical point.

The mass of the object is calculated at being 8,290,633,771,893,670,000 kg. The equatorial circumference of Phoebe is 669.2 km. The mean radius of Phoebe is 106.5 km. The surface area of Phoebe is 142,530.92 km2. The surface gravity of the said item is 0.049 m/s2. The average orbit velocity, that is the speed at which it orbits is 6,118.5 km/h.

The orbital inclination, the angle at which Phoebe orbits in relation to the orbital plane is 175.243 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.
