Sao is a Moon that orbits round the planet Neptune. Its orbit circumference, the total distance it travels round its planetary parent is 139,009,795.11 km. The furthest it gets from its orbital parent (apoasis) is 25,262,122 km. Its mass is estimated/calculated at being 89,920,105,985,831,600 kg. Its density has been calculated at being 1.5 g/cm3. Its volume is 44,602 km3.
Sao was discovered on 14 August 2002 by Tommy Grav, Matthew J. Holman, John J. Kavelaars, Wesley C. Fraser, and Dan Milisavljevic.
The orbital period, i.e. the period it takes to complete an orbit round Neptune is 2919.16 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 22,228,000 km, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Sao is 138.2 km. The mean radius, that is the average radius of Sao is 22.0 (assuming an albedo of 0.04) km. The surface area of Sao is 6,082.12 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 1,988.5 km/h.
The orbital inclination, the angle at which Sao orbits in relation to the orbital plane is 53.483 degrees. The orbital eccentricity is 0.1365, it is the degree at which Sao orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
