# Neso, Moon of Neptune

**Neso** 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 282,584,902.19 km. The furthest it gets from its orbital parent (apoasis) is 77,446,449 km. Its mass is estimated/calculated at being 164,853,527,640,691,000 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 2002 by Matthew J. Holman, John J. Kavelaars, Tommy Grav, Wesley C. Fraser, and Dan Milisavljevic.

The Semi-Major Axis of the orbit is 49,285,000 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 164,853,527,640,691,000 kg. The equatorial circumference of Neso is 188.5 km. The mean radius of Neso is 30.0 (assuming an albedo of 0.04) km. The surface area of Neso is 11,309.73 km2. The surface gravity of the said item is 0.012 m/s2. The average orbit velocity, that is the speed at which it orbits is 1,208.8 km/h.

The orbital inclination, the angle at which Neso orbits in relation to the orbital plane is 136.439 degrees. The orbital eccentricity is 0.5714, it is the degree at which Neso orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
