# Laomedeia, Moon of Neptune

**Laomedeia** 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 142,059,611.72 km. The furthest it gets from its orbital parent (apoasis) is 32,920,742 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 1.5 g/cm3. It was discovered on 13 August 2002 by Matthew J. Holman, John J. Kavelaars, Tommy Grav, Wesley C. Fraser, and Dan Milisavljevic.

The Semi-Major Axis of the orbit is 23,567,000 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 89,920,105,985,831,600 kg. The equatorial circumference of Laomedeia is 131.9 km. The mean radius of Laomedeia is 21.0 (assuming an albedo of 0.04) km. The surface area of Laomedeia is 5,541.77 km2. The surface gravity of the said item is 0.014 m/s2. The average orbit velocity, that is the speed at which it orbits is 1,866.5 km/h.

The orbital inclination, the angle at which Laomedeia orbits in relation to the orbital plane is 37.874 degrees. The orbital eccentricity is 0.3969, it is the degree at which Laomedeia orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
