# Iapetus, Moon of Saturn

**Iapetus** is a Moon that orbits round the planet Saturn. Its orbit circumference, the total distance it travels round its planetary parent is 22,368,684.06 km. The furthest it gets from its orbital parent (apoasis) is 3,665,184 km. Its mass is estimated/calculated at being 1,805,952,411,282,580,000,000 kg. Its density has been calculated at being 1.083 g/cm3. Its volume is 1.083 g/cm3. It was discovered in the year 1671 by G.D. Cassini.

The Semi-Major Axis of the orbit is 3,560,851 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 1,805,952,411,282,580,000,000 kg. The equatorial circumference of Iapetus is 4,621.9 km. The mean radius of Iapetus is 735.6 km. The surface area of Iapetus is 6,799,755.63 km2. The surface gravity of the said item is 0.223 m/s2. The average orbit velocity, that is the speed at which it orbits is 11,748.8 km/h.

The orbital inclination, the angle at which Iapetus orbits in relation to the orbital plane is 8.313 degrees. The orbital eccentricity is 0.0293, it is the degree at which Iapetus orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
