# Praxidike, Moon of Jupiter

**Praxidike** is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 131,098,561.00 km. The furthest it gets from its orbital parent (apoasis) is 26,016,270 km. Its mass is estimated/calculated at being 434,613,845,598,186 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 165 km3.

Praxidike was discovered on 23 November 2000 by Scott S. Sheppard, David C. Jewitt, Yanga R. Fernandez, and Eugene Magnier. Its orbital period, i.e. the period it takes to complete an orbit round Jupiter is 625.39 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 21,148,000 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 434,613,845,598,186 kg. The equatorial circumference of Praxidike is 21.4 km. The mean radius of Praxidike is 3.4 (assuming an albedo of 0.04) km. The surface area of Praxidike is 145.27 km2. The surface gravity of the said item is 0.003 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,734.5 km/h.

The orbital inclination, the angle at which Praxidike orbits in relation to the orbital plane is 148.985 degrees. The orbital eccentricity is 0.2302, it is the degree at which Praxidike orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
