Nereid, Moon of Neptune

Nereid is a Moon that orbits round Neptune rather than the Sun which our Earth orbits round. Its orbit circumference, the total distance it travels round its planetary parent is 29,067,053.44 km. The furthest it gets from its orbital parent (apoasis) is 9,653,041 km. Its mass is estimated/calculated at being 30,872,569,721,802,200,000 kg. Its density has been calculated at being 1.5 g/cm3. Its volume is 1.5 g/cm3. It was discovered in the year 1949 by G. Kuiper.

The Semi-Major Axis of the orbit is 5,513,818 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 30,872,569,721,802,200,000 kg. The equatorial circumference of Nereid is 1,068.1 km. The mean radius of Nereid is 170 km. The surface area of Nereid is 363,168.11 km2. The surface gravity of the said item is 0.071 m/s2. The average orbit velocity, that is the speed at which it orbits is 3,363.0 km/h.

The orbital inclination, the angle at which Nereid orbits in relation to the orbital plane is 7.09 degrees. The orbital eccentricity is 0.7507, it is the degree at which Nereid orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
