# Elara, Moon of Jupiter

**Elara** 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 72,891,344.30 km. The furthest it gets from its orbital parent (apoasis) is 14,293,493 km. Its mass is estimated/calculated at being 869,227,691,196,372,000 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 2.6 g/cm3. It was discovered in the year 1905 by Charles Dillon Perrine.

The Semi-Major Axis of the orbit is 11,741,000 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 869,227,691,196,372,000 kg. The equatorial circumference of Elara is 43.0 km. The mean radius of Elara is 43.0 (assuming an albedo of 0.04) km. The surface area of Elara is 23,235.22 km2. The surface gravity of the said item is 0.031 m/s2. The average orbit velocity, that is the speed at which it orbits is 11,697.5 km/h.

The orbital inclination, the angle at which Elara orbits in relation to the orbital plane is 26.627 degrees. The orbital eccentricity is 0.2174, it is the degree at which Elara orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
