Cressida, Moon of Uranus

Cressida is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 388,300.84 km. The furthest it gets from its orbital parent (apoasis) is 61,825 km. Its mass is estimated/calculated at being 343,195,071,179,257,000 kg. Its density has been calculated at being 1.3 g/cm3. Its volume is 264,081 km3.

Cressida was discovered on 9 January 1986 by Voyager 2. Its orbital period, i.e. the period it takes to complete an orbit round Uranus is 0.464 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 61,800 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 343,195,071,179,257,000 kg. The equatorial circumference of Cressida is 250.1 km. The mean radius of Cressida is 39.8 km. The surface area of Cressida is 19,905.63 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 34,869.0 km/h.

The orbital inclination, the angle at which Cressida orbits in relation to the orbital plane is 0.006 degrees. The orbital eccentricity is 0.0004, it is the degree at which Cressida orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
