Leda, Moon of Jupiter

Leda is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 69,679,979.34 km. The furthest it gets from its orbital parent (apoasis) is 12,991,594 km. Its mass is estimated/calculated at being 10,940,279,561,609,500 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 4,189 km3. It was discovered on 14 September 1974 by Charles T. Kowal.

The Semi-Major Axis of the orbit is 11,165,000 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 10,940,279,561,609,500 kg. The equatorial circumference of Leda is 62.8 km. The mean radius of Leda is 10.0 (assuming an albedo of 0.04) km. The surface area of Leda is 1,256.64 km2. The surface gravity of the said item is 0.007 m/s2. The average orbit velocity, that is the speed at which it orbits is 12,051.0 km/h.

The orbital inclination, the angle at which Leda orbits in relation to the orbital plane is 27.457 degrees. The orbital eccentricity is 0.1636, it is the degree at which Leda orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Himalia Group of Moons

Leda is a Himalia Jovian moon, what that means is that it belongs to the Himalia group of moons that orbit the planet Jupiter. The others are Himalia, Elara and Lysithea. All four moon are similar in structure and pattern. It is believed all four moons are from the same source, possibly the remnants of an asteroid that was involved in a collision. The remnants were pulled into orbit round the planet. It is the smallest of the group with Himalia from which the group gets its name is the largest. It takes about 241 days to orbit Jupiter. NASA

Legend of Leda

Leda was once a queen of Sparta and married to King Tyndareus. Leda was seduced by Zeus who had tricked her. The result would be two children Pollux and Helen. Another story has Zeus seduced nemesis who was a goose at the time where Zeus was a swan. The result of the seduction was an egg. The egg was brought to Leda where it hatched and Helen was born. Leda would raise Helen as her child. Theoi
