Adrastea, Moon of Jupiter

Adrastea is a Moon that orbits round Jupiter rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 810,530.25 km. The furthest it gets from its orbital parent (apoasis) is 129,232 km. Its mass is estimated/calculated at being 7,493,342,165,485,970 kg. Its density has been calculated at being 3 g/cm3. Its volume is 3 g/cm3. It was discovered in the year 1979 by D. Jewitt,.

The Semi-Major Axis of the orbit is 129,000 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 7,493,342,165,485,970 kg. The equatorial circumference of Adrastea is 51.5 km. The mean radius of Adrastea is 8.2 km. The surface area of Adrastea is 844.96 km2. The surface gravity of the said item is 0.007 m/s2. The average orbit velocity, that is the speed at which it orbits is 113,329.2 km/h.

The orbital inclination, the angle at which Adrastea orbits in relation to the orbital plane is 0.054 degrees. The orbital eccentricity is 0.0018, it is the degree at which Adrastea orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
