Thyone, Moon of Jupiter

Thyone is a Moon that orbits round the planet Jupiter. It is also know by other designations, JXXIX, S/2001 J2. Its mass is estimated/calculated at being 89,920,105,985,832 kg. Its density has been calculated at being 2.6. Its volume is 34.

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 627.3 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 2km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Escape Velocity of the object is 9 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 20940, 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 surface area of Thyone is 50.27. The surface gravity of the said item is 0.002. The Mean orbit velocity, that is the speed at which it orbits is 8719.60 km/h. The is the average distance in km of the object is from its parent 21192000.00.

The orbital inclination, the angle at which Thyone orbits in relation to the orbital plane is 148.5 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.
