Tethys, Moon of Saturn

Tethys is a Moon that orbits round Saturn rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 1,851,478.78 km. The furthest it gets from its orbital parent (apoasis) is 294,701 km. Its mass is estimated/calculated at being 617,551,805,221,061,000,000 kg. Its density has been calculated at being 0.973 g/cm3. Its volume is 0.973 g/cm3. It was discovered in the year 1684 by G.D. Cassini.

The Semi-Major Axis of the orbit is 294,672 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 617,551,805,221,061,000,000 kg. The equatorial circumference of Tethys is 3,348.9 km. The mean radius of Tethys is 533.0 km. The surface area of Tethys is 3,569,967.66 km2. The surface gravity of the said item is 0.145 m/s2. The average orbit velocity, that is the speed at which it orbits is 40,860.7 km/h.

The orbital inclination, the angle at which Tethys orbits in relation to the orbital plane is 1.091 degrees. The orbital eccentricity is 0.0001, it is the degree at which Tethys orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
