# Dione, Moon of Saturn

**Dione** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 2,371,365.51 km. The furthest it gets from its orbital parent (apoasis) is 378,245 km. Its mass is estimated/calculated at being 1,095,745,430,185,280,000,000 kg. Its density has been calculated at being 1.476 g/cm3. Its volume is 742,338,322 km3. It was discovered in the year 1684 by G.D. Cassini. Its orbital period, i.e. the period it takes to complete an orbit round Saturn is 2.737 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 377,415 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 1,095,745,430,185,280,000,000 kg. The equatorial circumference of Dione is 3,529.3 km. The mean radius of Dione is 561.7 km. The surface area of Dione is 3,964,776.51 km2. The surface gravity of the said item is 0.232 m/s2. The average orbit velocity, that is the speed at which it orbits is 36,100.4 km/h.

The orbital inclination, the angle at which Dione orbits in relation to the orbital plane is 0.028 degrees. The orbital eccentricity is 0.0022, it is the degree at which Dione orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
