Sponde, Moon of Jupiter

Sponde is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 145,740,935.31 km. The furthest it gets from its orbital parent (apoasis) is 31,241,028 km. Its mass is estimated/calculated at being 14,986,684,330,972 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 4 km3.

Sponde was discovered on 9 December 2001 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna. Its orbital period, i.e. the period it takes to complete an orbit round Jupiter is 748.32 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 23,790,000 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 14,986,684,330,972 kg. The equatorial circumference of Sponde is 6.3 km. The mean radius of Sponde is 1.0 (assuming an albedo of 0.04) km. The surface area of Sponde is 12.57 km2. The surface gravity of the said item is 0.001 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,115.0 km/h.

The orbital inclination, the angle at which Sponde orbits in relation to the orbital plane is 151.153 degrees. The orbital eccentricity is 0.3132, it is the degree at which Sponde orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
