S2003 / J4, Moon of Jupiter

S2003 / J4 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 145,466,560.91 km. The furthest it gets from its orbital parent (apoasis) is 32,441,582 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 2.6 g/cm3. It was discovered on February-March 2003 by Scott S. Sheppard, David C. Jewitt, Jan T. Kleyna, Yanga R. Fernandez, and Henry H. Hsieh.

The Semi-Major Axis of the orbit is 23,928,000 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 S2003 / J4 is 6.3 km. The mean radius of S2003 / J4 is 1.0 (assuming an albedo of 0.04) km. The surface area of S2003 / J4 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 8,025.6 km/h.

The orbital inclination, the angle at which S2003 / J4 orbits in relation to the orbital plane is 149.316 degrees. The orbital eccentricity is 0.3558, it is the degree at which S2003 / J4 orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
