Iapetus, Moon of Saturn

Iapetus is a Moon that orbits round the planet Saturn. 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. Its volume is 1667300080.

It was discovered in the year 1671 by G.D. Cassini.

The orbital period, i.e. the period it takes to complete an orbit round Saturn is 79.33018 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 736km. The value is the radius in km of the said object at the Equator.

The Escape Velocity of the object is 2,061 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 3561.3, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Iapetus is 4621.9 km. The surface area of Iapetus is 6,799,755.63. The surface gravity of the said item is 0.223. The Mean orbit velocity, that is the speed at which it orbits is 11748.80 km/h. The is the average distance in km of the object is from its parent 3560851.00.

The orbital inclination, the angle at which Iapetus orbits in relation to the orbital plane is 14.72 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.
