Laomedeia, Moon of Neptune

Laomedeia is a Moon that orbits round the planet Neptune. 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 38,792 km3.

Laomedeia was discovered on 13 August 2002 by Matthew J. Holman, John J. Kavelaars, Tommy Grav, Wesley C. Fraser, and Dan Milisavljevic. Its orbital period, i.e. the period it takes to complete an orbit round Neptune is 3175.62 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 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.

Voyager 2 Fly-by

Laomedeia is a small moon that orbits the planet of Neptune. It is so small that the Voyager 2 Space Probe missed it as it flew by because the moon is so small and distant from the planet. It has an orbit similar to Neptune compared to Halimede which orbits in the opposite direction to Neptune.

Laomedeia along with the other Neptunian moons would offer scientists a chance to look back at the early solar system. A voyage to Uranus is a long way off, New Scientist reports that a journey to the planet could start in the 2030s otherwise it'd be a long time before they would be able to get favourable planetary assist conditions.

Laomedeia Origins

Laomedeia along with similar moons, Sao and Halimede are believed to have been created from the remnants of a large moon that was destroyed during in collision between larger objects. The remnants were captured and have been in orbit ever since. NASA

Laomedeia Mythology

As Neptune is the Roman God of the Water, it was apt to name the moons after something to do with water. Like so many other moons of Neptune, it is named after a Nereid, a sea nymph. Laomedeia was "Leader of the Folk" Theoi
