Psamathe, Moon of Neptune

Psamathe is a Moon that orbits round the planet Neptune. It is also know by other designations, NX, S/2003 N1. Its mass is estimated/calculated at being 14,986,684,330,971,900 kg. Its density has been calculated at being 1.5. Its volume is 33510.

Psamathe was discovered on 29 August 2003 by Scott S. Sheppard, David C. Jewitt and Jan T. Kleyna.

The orbital period, i.e. the period it takes to complete an orbit round Neptune is 9374.0 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Equatorial Radius of the object is 20km. The Equatorial Radius is based on the assumption of the Albedo value. The value is the radius in km of the said object at the Equator.

The albedo of the object is 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Escape Velocity of the object is 36 km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 48390, which is the furthest point from the centre to the edge of an elliptical point.

The equatorial circumference of Psamathe is 125.7 km. The surface area of Psamathe is 5,026.55. The surface gravity of the said item is 0.003. The Mean orbit velocity, that is the speed at which it orbits is 1335.80 km/h. The is the average distance in km of the object is from its parent 48096000.00.

The orbital inclination, the angle at which Psamathe orbits in relation to the orbital plane is 132.6 degrees. The orbital eccentricity is 0.3809, it is the degree at which Psamathe orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
