Galatea is a Moon that orbits round the planet Neptune. Its orbit circumference, the total distance it travels round its planetary parent is 389,262.18 km. The furthest it gets from its orbital parent (apoasis) is 61,959 km. Its mass is estimated/calculated at being 3,746,671,082,742,980,000 kg. Its density has been calculated at being 1.3 g/cm3. Its volume is 2,854,543 km3.
It was discovered in the year 1989 by S. Synnott, Voyager 2.
The orbital period, i.e. the period it takes to complete an orbit round Neptune is 0.429 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 61,953 km, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Galatea is 552.9 km. The mean radius, that is the average radius of Galatea is 88.0 km. The surface area of Galatea is 97,313.97 km2. The surface gravity of the said item is 0.032 m/s2. The average orbit velocity, that is the speed at which it orbits is 37,807.1 km/h.
The orbital eccentricity is 0.0001, it is the degree at which Galatea orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
