Lysithea is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 73,387,003.90 km. The furthest it gets from its orbital parent (apoasis) is 13,033,991 km. Its mass is estimated/calculated at being 62,944,074,190,082,100 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 24,429 km3.
Lysithea was discovered on 6 July 1938 by Seth Barnes Nicholson. Its orbital period, i.e. the period it takes to complete an orbit round Jupiter is 259.2 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 11,717,000 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 62,944,074,190,082,100 kg. The equatorial circumference of Lysithea is 113.1 km. The mean radius of Lysithea is 18.0 (assuming an albedo of 0.04) km. The surface area of Lysithea is 4,071.50 km2. The surface gravity of the said item is 0.013 m/s2. The average orbit velocity, that is the speed at which it orbits is 11,797.0 km/h.
The orbital inclination, the angle at which Lysithea orbits in relation to the orbital plane is 28.302 degrees. The orbital eccentricity is 0.1124, it is the degree at which Lysithea orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
Lysithea is a Hamilia moon, that is a moon that has the same characteristics as Hamilia, the largest of the group. It is believed, the others Elara, Hamilia and Leda are all from the same source, remnants of an asteroid that was once destroyed in a collision and that the resulting debris were captured and put into orbit. It is the second smallest member of the Hamilia group with Hamilia being the largest then Elara and finally Leda.
Lysithea was one of many lovers of Zeus. As he had got Lysithea pregnant, he promised to do whatever Lysithea asked of him. Hera, Zeus' wife tricked Lysithea into getting Zeus to come to Lysithea in the same way Zeus wooed Hera. When Zeus came, he accidentally set the room alight and caused Lysithea to die of fright. Zeus managed to save the baby foetus and he sew it into his thigh. When the baby reached birthing time, he undone the stitches and out popped Dionysus.
