# Hegemone, Moon of Jupiter

**Hegemone** is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 143,589,402.13 km. The furthest it gets from its orbital parent (apoasis) is 31,670,347 km. Its mass is estimated/calculated at being 44,960,052,992,916 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 2.6 g/cm3. It was discovered on 8 February 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 23,566,000 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 44,960,052,992,916 kg. The equatorial circumference of Hegemone is 9.4 km. The mean radius of Hegemone is 1.5 (assuming an albedo of 0.04) km. The surface area of Hegemone is 28.27 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 8,086.6 km/h.

The orbital inclination, the angle at which Hegemone orbits in relation to the orbital plane is 153.977 degrees. The orbital eccentricity is 0.3439, it is the degree at which Hegemone orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
