Erinome, Moon of Jupiter

Erinome is a Moon that orbits round the planet Jupiter. Its orbit circumference, the total distance it travels round its planetary parent is 143,676,263.20 km. The furthest it gets from its orbital parent (apoasis) is 29,466,965 km. Its mass is estimated/calculated at being 44,960,052,992,916 kg. Its density has been calculated at being 2.6 g/cm3. Its volume is 17 km3.

Erinome was discovered on 23 November 2000 by Scott S. Sheppard, David C. Jewitt, Yanga R. Fernandez, and Eugene Magnier.

The orbital period, i.e. the period it takes to complete an orbit round Jupiter is 728.49 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 23,283,000 km, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Erinome is 10.1 km. The mean radius, that is the average radius of Erinome is 1.6 (assuming an albedo of 0.04) km. The surface area of Erinome is 32.17 km2. The surface gravity of the said item is 0.001 m/s2. The average orbit velocity, that is the speed at which it orbits is 8,218.0 km/h.

The orbital inclination, the angle at which Erinome orbits in relation to the orbital plane is 164.921 degrees. The orbital eccentricity is 0.2656, it is the degree at which Erinome orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Carme Moon Group

Carme is the largest of the group of Jovian moons referred to as the Carme group. They have all been grouped together because it is believed they all shared the same common source. In addition to the supposed common source, all the members of the group are non-spherical and retrograde, that is they all orbit the planet Jupiter in the opposite direction that Jupiter rotates. As they are all retrograde in the group, they all end with the letter "e" as dictated by the International Astronomical Union, the international body that defines the names. Although some names have not yet been agreed upon. Kiddle
