Thyone, Moon of Jupiter

Thyone is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 131,252,020.60 km. The furthest it gets from its orbital parent (apoasis) is 26,229,338 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.

Thyone was discovered on 11 December 2001 by Scott S. Sheppard, David C. Jewitt, and Jan T. Kleyna.

The orbital period, i.e. the period it takes to complete an orbit round Jupiter is 627.19 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 21,192,000 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Thyone is 12.6 km. The mean radius, that is the average radius of Thyone is 2.0 (assuming an albedo of 0.04) km. The surface area of Thyone 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 8,719.6 km/h.

The orbital inclination, the angle at which Thyone orbits in relation to the orbital plane is 148.819 degrees. The orbital eccentricity is 0.2377, it is the degree at which Thyone orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Ananke Moon Group

Ananke group of Jovian moons are all believed to have the same source, probably the result of a asteroid collision. The remnants were caught by the immense gravitational pull of Jupiter and remain in orbit ever since. The name derives it name from the largest in the group. All the members of the group orbit in a retrograde orbit hence why they all finish with the letter 'e' in their name.
