# Rhea, Moon of Saturn

**Rhea** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 3,311,665.09 km. The furthest it gets from its orbital parent (apoasis) is 527,595 km. Its mass is estimated/calculated at being 2,307,089,151,289,080,000,000 kg. Its density has been calculated at being 1.233 g/cm3. Its volume is 1,870,166,133 km3. It was discovered in the year 1672 by G.D. Cassini. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 4.518 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 527,068 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 2,307,089,151,289,080,000,000 kg. The equatorial circumference of Rhea is 4,802.2 km. The mean radius of Rhea is 764.3 km. The surface area of Rhea is 7,340,701.82 km2. The surface gravity of the said item is 0.264 m/s2. The average orbit velocity, that is the speed at which it orbits is 30,541.4 km/h.

The orbital inclination, the angle at which Rhea orbits in relation to the orbital plane is 0.333 degrees. The orbital eccentricity is 0.001, it is the degree at which Rhea orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
