# Hermippe, Moon of Jupiter

**Hermippe** 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 132,310,864.30 km. The furthest it gets from its orbital parent (apoasis) is 25,821,990 km. Its density has been calculated at being 2.6 g/cm3. Its volume is 2.6 g/cm3. It was discovered on 9 December 2001 by Scott S. Sheppard, David C. Jewitt, and Jan T. Kleyna.

The Semi-Major Axis of the orbit is 21,300,000 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Hermippe is 12.6 km. The mean radius of Hermippe is 2.0 (assuming an albedo of 0.04) km. The surface area of Hermippe is 50.27 km2. The surface gravity of the said item is 0.002 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,696.9 km/h.

The orbital inclination, the angle at which Hermippe orbits in relation to the orbital plane is 150.887 degrees. The orbital eccentricity is 0.2123, it is the degree at which Hermippe orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
