Stephano, Moon of Uranus

Stephano is a Moon that orbits round the planet Uranus. Its orbit circumference, the total distance it travels round its planetary parent is 49,670,195.34 km. The furthest it gets from its orbital parent (apoasis) is 9,807,464 km. Its mass is estimated/calculated at being 25,477,363,362,652,300 kg. Its density has been calculated at being 1.5 g/cm3. Its volume is 17,157 km3.

Stephano was discovered on 18 July 1999 by Brett Gladman, Matthew Holman, John J. Kavelaars, Jean-Marc Petit, and Hans Scholl. Its orbital period, i.e. the period it takes to complete an orbit round Uranus is 677.47 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 8,007,400 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 25,477,363,362,652,300 kg. The equatorial circumference of Stephano is 100.5 km. The mean radius of Stephano is 16.0 (assuming an albedo of 0.04) km. The surface area of Stephano is 3,216.99 km2. The surface gravity of the said item is 0.007 m/s2. The average orbit velocity, that is the speed at which it orbits is 3,054.9 km/h.

The orbital inclination, the angle at which Stephano orbits in relation to the orbital plane is 143.819 degrees. The orbital eccentricity is 0.2248, it is the degree at which Stephano orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
