Thalassa is a Moon that orbits round the planet Neptune. Its orbit circumference, the total distance it travels round its planetary parent is 314,624.22 km. The furthest it gets from its orbital parent (apoasis) is 50,084 km. Its mass is estimated/calculated at being 374,667,108,274,298,000 kg. Its density has been calculated at being 1.3 g/cm3. Its volume is 288,696 km3.
It was discovered in the year 1989 by R. Terrile, Voyager 2.
The orbital period, i.e. the period it takes to complete an orbit round Neptune is 0.311 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 50,074 km, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Thalassa is 257.6 km. The mean radius, that is the average radius of Thalassa is 41.0 km. The surface area of Thalassa is 21,124.07 km2. The surface gravity of the said item is 0.015 m/s2. The average orbit velocity, that is the speed at which it orbits is 42,152.2 km/h.
The orbital inclination, the angle at which Thalassa orbits in relation to the orbital plane is 0.135 degrees. The orbital eccentricity is 0.0002, it is the degree at which Thalassa orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
