Thalassa is a Moon that orbits round the planet Neptune. Its mass is estimated/calculated at being 374,667,108,274,298,000 kg. Its density has been calculated at being 1.3. Its volume is 288696.
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 0.31149 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 41km. The value is the radius in km of the said object at the Equator.
The Escape Velocity of the object is 126 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 50.075, 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 surface area of Thalassa is 21,124.07. The surface gravity of the said item is 0.015. The Mean orbit velocity, that is the speed at which it orbits is 42152.20 km/h. The is the average distance in km of the object is from its parent 50074.00.
The orbital inclination, the angle at which Thalassa orbits in relation to the orbital plane is 0.21 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.
