Ananke is a Moon that orbits round Jupiter rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 131,676,895.83 km. The furthest it gets from its orbital parent (apoasis) is 26,456,706 km. Its mass is estimated/calculated at being 29,973,368,661,943,900 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 2.6 g/cm3. It was discovered on 28 September 1951 by Seth Barnes Nicholson.
The Semi-Major Axis of the orbit is 21,276,000 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 29,973,368,661,943,900 kg. The equatorial circumference of Ananke is 88.0 km. The mean radius of Ananke is 14.0 (assuming an albedo of 0.04) km. The surface area of Ananke is 2,463.01 km2. The surface gravity of the said item is 0.010 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,712.0 km/h.
The orbital inclination, the angle at which Ananke orbits in relation to the orbital plane is 148.889 degrees. The orbital eccentricity is 0.2435, it is the degree at which Ananke orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
