# Arche, Moon of Jupiter

**Arche** 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 144,318,784.67 km. The furthest it gets from its orbital parent (apoasis) is 29,322,203 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 10/31/2002 by Scott S. Sheppard.

The Semi-Major Axis of the orbit is 23,355,000 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 Arche is 9.4 km. The mean radius of Arche is 1.5 (assuming an albedo of 0.04) km. The surface area of Arche 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 8,216.0 km/h.

The orbital inclination, the angle at which Arche orbits in relation to the orbital plane is 163.937 degrees. The orbital eccentricity is 0.2555, it is the degree at which Arche orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
