Pasiphae, Moon of Jupiter

Pasiphae is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 142,016,762.95 km. The furthest it gets from its orbital parent (apoasis) is 33,286,216 km. Its mass is estimated/calculated at being 299,733,686,619,439,000 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 113,097 km3.

Pasiphae was discovered on 27 January 1908 by Philibert Jacques Melotte.

The orbital period, i.e. the period it takes to complete an orbit round Jupiter is 743.61 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 23,624,000 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Pasiphae is 188.5 km. The mean radius, that is the average radius of Pasiphae is 30.0 (assuming an albedo of 0.04) km. The surface area of Pasiphae is 11,309.73 km2. The surface gravity of the said item is 0.022 m/s2. The average orbit velocity, that is the speed at which it orbits is 7,957.4 km/h.

The orbital inclination, the angle at which Pasiphae orbits in relation to the orbital plane is 151.431 degrees. The orbital eccentricity is 0.409, it is the degree at which Pasiphae orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Pasiphae Mythology Legend

Pasiphae is the wife of King Minos of Crete. Pasiphae had an affair with Zeus, king of the Greek Gods and produced a son, Ammon. Her story is more tragic, Pasiphae was forced to make love to a bull by Poseidon. The result of the consumation was Minotaur, the half-bull, half-man flesh eating monster that was forced to live in the Labyrinth. The bull would eventually be killed by Theseus, a Greek hero.

Pasiphae Moon Group

Pasiphae group of Jovian Moons are all believed to have been created from the same source, notably through the result of an asteroid collision. The remnants were captured by Jupiters immense gravity and became satellites.

The largest of the group is Pasiphae from which the group gets it name from. Although, believed to be the result of a collision, confidence in this is lower than other groups because amongst other things, they all have differing colours, eccentricity and inclination.

There is doubt as to whether Sinope is from the same source as the others. It may exhibit some of the characteristics but there is more to indiciate that its source is elsewhere. Pasiphae contains 99% of the mass of the group without Sinope being included, otherwise it is down to 87% N.A.S.A.
