Autonoe, Moon of Jupiter

Autonoe is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 147,145,544.12 km. The furthest it gets from its orbital parent (apoasis) is 31,641,848 km. Its mass is estimated/calculated at being 89,920,105,985,832 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 34 km3. It was discovered on 10 December 2001 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna.

The Semi-Major Axis of the orbit is 24,033,000 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 89,920,105,985,832 kg. The equatorial circumference of Autonoe is 12.6 km. The mean radius of Autonoe is 2.0 (assuming an albedo of 0.04) km. The surface area of Autonoe is 50.27 km2. The surface gravity of the said item is 0.002 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,056.6 km/h.

The orbital inclination, the angle at which Autonoe orbits in relation to the orbital plane is 152.284 degrees. The orbital eccentricity is 0.3166, it is the degree at which Autonoe orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Legend of Autonoe

Autonoe was an ancient Greek Goddess who was the daughter of King Cadmus of Thebes and the goddess Harmonia. Thebes is a city in southern mainland Greece, that is you exclude the Greek Islands. Autonoe married Aristaeus who was a minor Greek God and had two children, Actaeon and Macris. Greek Mythology

The name Autonoe was chosen because it ends with the letter "e". According to NASA, moons that are retrograde in orbit end with the letter "e". The link at the time of writing referred to Jupiter but Jupiter is Roman whereas Autonoe is a Greek Legend.
